GENERAL DESCRIPTION
The Z86KXX Keyboard Controllers are full-featured members of the Z8(R) MCU family offering a unique register-toregister architecture that avoids accumulator bottlenecks and is more code efficient than RISC processors. For keyboard applications demanding powerful I/O capabilities, the Z86KXX provides 32 pins dedicated to input and output for row, column, clock, data, and LEDs. The on-chip counter/timer is available to relieve the system of administering real-time tasks. Five different internal or external interrupt sources are maskable and prioritized in which a vectored address is provided for efficient interrupt subroutine handling and multitasking functions. The Z86K15 achieves low EMI by means of several modifications in the output drivers and clock circuitry of the device.

Zilog Program Memory. The 16-bit program counter addresses 4 KB of program memory space at internal locations (Figure 11). The first 12 bytes of program memory are reserved for the interrupt vectors. These locations have six 16-bit vectors that correspond to the five available interrupts. Byte 12 to byte 4095* consists of on-chip, mask programmed ROM. Addresses 4096* and greater are reserved.

Z86K13/K14/K15/K16/K17/K18 CMOS Z8(R) 8-Bit MCU Keyboard Controllers Register File. The register file (Figure 13) consists of four I/O port registers, 188 general-purpose registers (excluding P00-P03), and 11 control and status registers (R3-R0, R191-R4, and R255-R240, respectively). The instructions can access registers directly or indirectly through an 8-bit address field. This allows short, 4-bit register addressing using the Register Pointer. In the 4-bit mode, the register file is divided into nine working-register groups, each occupying 16 continuous locations. The Register Pointer addresses the starting location of the active working-register group.

Zilog Counter/Timers. There is an 8-bit programmable counter/timer (T0) driven by its own 6-bit programmable prescaler (Figure 15). The 6-bit prescalers can divide the input frequency of the clock source by any integer number from 1 to 64. The prescaler drives its counter, which decrements the value (1 to 256) on the prescaler overflow. When both the counter and prescaler reach the end of count, a timer interrupt request, IRQ4, is generated.
Z86K13/K14/K15/K16/K17/K18 CMOS Z8(R) 8-Bit MCU Keyboard Controllers The counter can be programmed to start, stop, restart to continue, or restart from the initial value. The counter can also be programmed to stop upon reaching zero (single pass mode) or to automatically reload the initial value and continue counting (modulo-n continuous mode) The counter, but not the prescaler, is read at any time without disturbing its value or count mode.

Interrupts. The Z86K15 has five different interrupts from five different sources. These interrupts are maskable and prioritized (Figure 16). The five sources are divided as follows: four sources are claimed by Port 3 lines P33-P30, and the other is claimed by the counter/timer. The Interrupt Masked Register globally or individually enables or disables the five interrupts requests. When more than one interrupt is pending, priorities are resolved by a programmable priority encoder that is controlled by the Interrupt Priority register. All interrupts are vectored through locations in the program memory. When an interrupt machine cycle is activated an interrupt request is granted. Thus, this disables all of the subsequent interrupts, saves the Program Counter and status flags, and then branches to the program memory vector location reserved for that interrupt. This memory location and the next byte contain the 16-bit address of the interrupt service routine for that particular interrupt request. To accommodate polled interrupt systems, interrupt inputs are masked and the interrupt request register is polled to determine which of the interrupt request needs service. RC Oscillator. The Z86K13/14/15 provides an internal capacitor to accommodate an RC oscillator configuration. A 1% precision resistor is necessary to achieve 10% accurate frequency oscillation.

Zilog Watch-Dog Timer. The Watch-Dog Timer is activated automatically by power-on if it is enabled in the Mask Option. The WDT is a retriggerable one-shot timer that resets the Z8 if it reaches its terminal count. The WDT is driven by the system clock. It must be refreshed at least once during each time cycle by executing the WDT instruction. WDT can be enabled by Mask Option. (Figure 18) WDT Hot bit. Bit 7 of the Interrupt Request register (IRQ register FAH) determines whether a hot start or cold start occurred. A cold start is defined as reset occurring from
Z86K13/K14/K15/K16/K17/K18 CMOS Z8(R) 8-Bit MCU Keyboard Controllers power-up of the Z86K15 (the default upon power-up is 0). A hot start occurs when a WDT time-out has occurred (bit 7 is set to 1). Bit 7 of the IRQ register is read-only and is automatically reset to 0 when read. Watch-Dog Timer . The WDT time-out is ----------------------------. f ( Hz ) WDT During HALT (D5-R250). This bit determines whether or not the WDT is active during HALT Mode. The default is 1, and a 1 indicates active during HALT.

Power-On-Reset (POR). A timer circuit is triggered by the system oscillator and is used for the Power-On Reset (POR) timer function. The POR time allows VCC and the oscillator circuit to stabilize before instruction execution begins. POR period is defined as: POR (ms) = 589824 f(Hz) FF 6F FF 7F NOP STOP NOP HALT ; clear the pipeline ; enter STOP Mode or ; clear the pipeline ; enter HALT Mode
R250 IRQ D7 D6 D5 D4 D3 D2 D1 D0
The POR timer circuit is a one-shot timer triggered by one of two conditions: 1. Power fail to Power OK status 2. Stop-Mode Recovery The POR time is a nominal 147 ms 10%. At 4 MHz the POR timer is bypassed after Stop-Mode Recovery. HALT. HALT turns off the internal CPU clock, but not the RC oscillator. The counter/timer and external interrupts IRQ0, IRQ1, IRQ2, and IRQ3 remain active. The Z86K15 is recovered by interrupts, either externally or internally (Figure 19). STOP. This instruction turns off the internal clock and oscillator. It reduces the standby current to less than 10 A. The STOP Mode is terminated by a reset only or external reset. This causes the processor to restart the application program at address 000C (HEX) or the active external interrupt vector. In order to enter STOP (or HALT) Mode, it is necessary to first flush the instruction pipeline to avoid suspending execution in mid-instruction. To do this, the user must execute a NOP (Opcode=FFH) immediately before the appropriate sleep instruction, such as:
IRQ0 = P32 Input IRQ1 = P33 Input IRQ2 = P31 Input IRQ3 = P30 Input IRQ4 = TO WDT during HALT 0 OFF * 1 ON Stop Flag 0 POR/WDT* 1 Stop Recovery WDT Hot Bit (Read Only) 0 POR* 1 WDT Timeout
* On RESET
Figure 19. IRQ Register The Bit 6 of IRQ Registers are flags for STOP Mode Recovery (Figure 20). Cold or Warm Start (D6). This bit is set upon entering STOP Mode. A 0 (cold) indicates that the device is awakened by a POR/WDT RESET. A 1 (warm) indicates that the device is awakened by a SMR source. This bit is reset when read. Negative transition on any of the designated row input pins or host data line will recover Z86KXX from STOP Mode.
