Command Set/Reset Status Indicators Echo Invalid Command Select Alternate Scan Codes Invalid Command Read ID Set Typematic Rate/Delay Enable Default Disable Set Default Set All Keys - Typematic Set All Keys - Make/Break Set All Keys - Make Set All Keys - Typematic/Make/Break Set Key Type - Typematic Set Key Type - Make/Break Set Key Type - Make Resend Reset Hex Value ED EE EF F0 F1 F2 F3 F4 F5 F6 F7 F8 F9 FA FB FC FD FE FF EFH and F1H - Invalid Command EFH and F1H are invalid commands and are not supported. If HT82K629A receives one of these and sends it, the HT82K629A will not acknowledge the command, but returns a Resend command and continues in its previous scanning state. F0H - Select Alternate Scan Codes This command instructs the HT82K629A to select one of the two sets of scan codes. The HT82K629A acknowledges receipt of this command with ACK, clears both the output buffer and the typematic key. The host then sends the option byte and the keyboard responds with another ACK. An option byte value of hex 01 selects scan code set 1, hex 02 selects set 2. An option byte value of hex 00 causes the HT82K629A to acknowledge with ACK and sends a byte telling the host which scan code set is currently in use. After establishing the new scan code set, the HT82K629A returns to the scanning state it was in before receiving the Select Alternate Scan Codes command. F2H - Read ID This command requests identification information from the HT82K629A. The HT82K629A responds with ACK, discontinues scanning and sends the two keyboard ID bytes hex 83h and ABh. After the output of the second ID byte, the HT82K629A resumes scanning. The HT82K629A responds to the option byte with ACK, sets the indicators and if the HT82K629A was previously enabled, continues scanning. The status of the indicators will reflect the bits in the option byte and can be activated or deactivated in any combination. If another command is received in place of the option byte, execution of the Set/Reset Mode Indicators command is stopped, with no change to the indicator status, and the new command is processed. Immediately after power-on, the lights default to the off state. If the Set Default and Default Disable commands are received, the lamps remain in the state they were in before the command was received. EEH - Echo Echo is a diagnostic aid. When the HT82K629A receives this command, it issues a hex EE response and if the HT82K629A was previously enabled, continues scanning. The commands may be sent to the HT82K629A at any time and the HT82K629A will respond within 25ms except when performing the internal diagnostics or executing a Reset command. EDH - Set/Reset Status Indicators Three status indicators on the keyboard-Num Lock, Caps Lock, and Scroll Lock-are accessible by the host. The HT82K629A activates or deactivates these indicators when it receives a valid command-code sequence from the system. The command sequence begins with the command byte (hex ED). The HT82K629A responds to the command byte with ACK, discontinues scanning, assignments for this option byte are as follow: Bit 0 1 2 3~7 Indicator Scroll Lock Indicator Num Lock Indicator Caps Lock Indicator Reserved (Must be 0) If a bit for an indicator is set to 1, the indicator is turned on. If a bit is set to 0, the indicator is turned off. Rev. 1.00 4 December 8, 2003 HT82K629A F3H - Set Typematic Rate/Delay The host issues the Set Typematic Rate/Delay command to change the typematic rate and delay. The HT82K629A responds to the command with ACK, stops scanning and waits for the system to issue the rate/delay value byte. The HT82K629A responds to the value byte with another ACK, sets the rate and delay to the value indicated, and continues scanning (if it was previously enabled). Bits 6 and 5 indicate the delay, and bits 4, 3, 2, 1 and 0 indicate the rate. Bit7 is always 0. The delay is equal to 1 plus the binary value bit 6 and 5, multiplied by 250ms20%. The period (interval from one typematic output to the next) is determined by the following equation: Period = (8+A)*(2^B)*0.00417 seconds. Where: A = binary value of bits 2, 1, and 0. B = binary value of bits 4, and 3. The typematic rate is 1 for each period and are listed as follows: Bit 00000 00001 00010 00011 00100 00101 00110 00111 01000 01001 01010 01011 01100 01101 01110 01111 Typematic Rate 20% 30.0 26.7 24.0 21.8 20.0 18.5 17.1 16.0 15.0 13.3 12.0 10.9 10.0 9.2 8.0 8.0 Bit 10000 10001 10010 10011 10100 10101 10110 10111 11000 11001 11010 11011 11100 11101 11110 11111 Typematic Rate 20% 7.5 6.7 6.0 5.5 5.0 4.6 4.3 4.0 3.7 3.3 3.0 2.7 2.5 2.3 2.1 2.0 FEH - Resend The host sends this command when it detects an error in any transmission from the HT82K629A. It is sent only after a data transmission and before the host allows the next data output. When a Resend is received, the HT82K629A sends the previous output again (unless the previous output was Resent, in which case the HT82K629A sends the last byte before the Resend command). F7H, F8H, F9H, FAH - Set All Keys Since HT82K629A do not support keyboard code set 3 format, so it will not acknowledge the command but returns a Resend command and continues in its previous scanning state. FBH, FCH, FDH - Set Key Type Since HT82K629A do not support keyboard code set 3 format, so it will not acknowledge the command but returns a Resend command and continues in its previous scanning state. F4H - Enable Upon receipt of this command, the HT82K629A will respond with ACK, clears its output buffer, clears the last typematic key, and starts scanning. F5H - Default Disable The Default Disable command resets all conditions to the power on default states. The HT82K629A will respond with ACK, clears its output buffer, sets the default typematic rate/delay, and clears the last typematic key. The HT82K629A then stops scanning and awaits further command. F6H - Set Default The Set Default command resets all conditions to the power on default states. The HT82K629A will respond with ACK, clears its output buffer, sets the default key typematic rate/delay, and clears the last typematic key then continues scanning. The default values for the HT82K629A are as follows: Typematic rate= 10.9 characters per second 20% Delay = 500ms20% The execution of this command stops without changes to the existing rate if another command is received instead of the rate/delay value byte. Rev. 1.00 5 December 8, 2003 HT82K629A Commands to the Host The following table shows the commands that the HT82K629A may send to the host and their hexadecimal values. Command Key Detection Error/Overrun Keyboard ID Bat Completion Code Bat Failure Core Echo Acknowledge Resend Key Detection Error/Overrun Hex Value 00 (Code Set 2) 83AB AA FC EE FA FE FF (Code Set 1) Data Communications * Data output If CLK=0, no transmission (keyboard is inhibited). If CLK=1, DATA=0, no transmission (system request to send). If CLK=1, DATA=1, transmission permitted. Data will be valid before the trailing edge and beyond the leading edge of the clock. The KB checks the clock line for an active level every 60ms. If line contention occurs (system brings the clock low before the tenth clock), set clock=data=high. The system overrides the clock line for at least 60ms. The keyboard checks the clock line state at intervals of 10ms. If a system request-to-send is detected, the keyboard counts 11 data bits. Data will be valid before the rising edge and beyond the falling edge. After the 10th bit, the keyboard checks for an active level on the data line. If the line is active it is forced to be inactive, and counts one more bits. Note: This action signals the system that the keyboard has received its data. Upon reception of this signal, the system returns to the ready state, in which it can accept keyboard outputs or goes to the inhibit state until it is ready. * Data input 00H or FFH - Key Detection Error The HT82K629A sends a key detection error character if conditions in the keyboard make it impossible to identify a switch closure. If the HT82K629A is using scan code set 1, the code is FFH. For sets 2, the code is 00H. 00H or FFH - Overrun An overrun character is placed in the HT82K629A buffer and replaces the last code when the buffer capacity has been exceeded. The code is sent to the host when it reaches the top of the buffer queue. If the HT82K629A is using scan code set 1, the code is FFH. For sets 2, the code is 00H. 83AbH - Keyboard ID The keyboard ID consists of 2 bytes, Hex 83AbH. The HT82K629A responds to the Read ID with ACK, discontinues scanning and sends 2 ID bytes. The low byte is sent first followed by the high byte. Following the output of Keyboard ID, the HT82K629A begins scanning. EEH - Echo The HT82K629A sends this code in response to an Echo command. AAH - BAT Completion Code Following a satisfactory completion of the BAT, the HT82K629A sends AAH. Any other code indicates keyboard failure. FCH - BAT Failure Code If a BAT failure occurs, the HT82K629A sends this code, discontinues scanning and waits for a host response or reset. FEH - Resend The HT82K629A issues a Resend command following receipt of an invalid input or any input with incorrect parity. If the host sends nothing to the HT82K629A, no response is required. Rev. 1.00 6 If the keyboard data line is found to be at an inactive level following the 10th bit, a frame error has occurred, and the keyboard continues to count until the data line becomes active. The keyboard then makes the data line inactive and sends a Resend. Data Stream Mode 1,2,3 B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 B11 Note: Start bit (always 0) Data bit 0 Data bit 1 Data bit 2 Data bit 3 Data bit 4 Data bit 5 Data bit 6 Data bit 7 Parity bit (odd par) Stop bit (always 1) The parity bit is either 1 or 0, and the 8 data bits, plus the parity bit, always have an odd number of 1ms.
