Watch-Dog Timer Mode Register (WDTMR)
The WDT is a retriggerable, one-shot timer that resets the Z8 if it reaches its ter-
minal count. The WDT must initially be enabled by executing the WDT instruction.
On subsequent executions of the WDT instruction, the WDT circuit is refreshed.
The WDT circuit is driven by an on-board RC oscillator or external oscillator from
the XTAL1 pin. The WDT instruction affects the Zero (Z), Sign (S), and Overflow
(V) flags.
The POR clock source is selected with bit 4 of the WDT register. Bits 0 and 1 con-
trol a tap circuit that determines the minimum time-out period. Bit 2 determines
whether the WDT is active during HALT, and Bit 3 determines WDT activity during
STOP. Bits 5 through 7 are reserved (Figure 51). This register is accessible only
during the first 60 processor cycles (122 XTAL clocks) from the execution of the
first instruction after Power-On-Reset, Watch-Dog Reset, or a Stop-Mode Recov-
ery (Figure 51). After this point, the register cannot be modified by any means,
intentional or otherwise. The WDTMR cannot be read. The register is located in
Bank F of the Expanded Register Group at address location 0FH. The WDTMR is
organized as shown in Figure 51.
