usar genikey tm ur3hcgnk preliminary usar geni tm usb ic family product specifications keyboard scanner the encoder scans and debounces an 8 row by 16 column matrix keyboard. the usar genikey tm provides internal pull- ups for the row input pins. when active, the encoder selects one of the column lines (c0-c15) and then reads the row data lines (r0- r7). a key closure is detected as a zero in the corresponding position of the matrix. a complete scan cycle for the entire keyboard takes approximately 10 ms. each key found pressed is debounced for a period of 20 ms. once the key is verified, the corresponding key code(s) are loaded into the transmit buffer of the usb communication channel. ps/2 port the ps/2 port allows the user to connect legacy ps/2 devices to the usb host system. standard 104 keyboards and ps/2 mice, with support for mousewheel, can be hot-plugged and immediately begin communicating with the host. usb descriptors, cont. usar ? a semtech company datasheet doc3-gnk-ds-101 5 usar ? a semtech company offset part size value description endpoint descriptor 0 blength 1 0x07 size of endpoint descriptor in bytes 1 bdescriptortype 1 0x05 endpoint descriptor type 2 bendpointaddress 1 0x81 endpoint address (in, endpoint 1) 3 bmattribute 1 0x03 endpoint's attribute (interrupt) 4 wmaxpacketsize 2 0x0008 maximum packet size 6 binterval 1 0x0a interval for polling endpoint (poll every 10 milliseconds) offset part size value description string descriptor 1 blength 1 0x04 length of string description in bytes 2 bdescriptortype 1 0x03 descriptor type = string 3 bstring 2 0x0904 langid code = english 5 blength 1 0x0a length of string descriptor 6 bdescriptortype 1 0x03 descriptor type = string 7 bstring 8 ? u ? ,0, ? s ? , manufacturer 0, ? a ? ,0, ? r ? ,0 15 blength 1 0x16 length of string descriptor 16 bdescriptortype 1 0x03 descriptor type = string 17 bstring 20 ? g ? ,0, ? e ? product 0, ? n ? ,0, ? i ? 0, ? k ? ,0 , ? e ? ,0, ? y ? 0, ? ? ,0, ? t ? 0, ? m ? ,0 offset data mnemonic value report descriptor 0 05 01 usage page generic desktop 2 09 06 usage keyboard 4 a1 01 collection application 6 85 01 report id 01 8 05 07 usage page key codes 10 19 e0 usage minimum 224 12 29 e7 usage maximum 231 14 15 00 logical minimum 0 16 25 01 logical maximum 1 18 75 01 report size 1 20 95 08 report count 8 22 81 02 input data, variable, absolute 24 95 01 report count 1 26 75 08 report size 8 28 81 01 input constant 30 95 05 report count 5 32 75 01 report size 1 34 05 08 usage page page # for leds 36 19 01 usage minimum 1 38 29 05 usage maximum 5 40 91 02 output data, variable, absolute 42 95 01 report count 1
