Watch-Dog Timer Mode Register (WDTMR).
The WDT
is a retriggerable one-shot timer that resets the Z8 if it
reaches its terminal count. The WDT is initially enabled by
executing the WDT instruction and refreshed on subse-
quent executions of the WDT instruction. The WDT circuit
is driven by an on-board RC oscillator or external oscillator
from the XTAL1 pin. The POR clock source is selected
with bit 4 of the WDT register (Figure 38).
WDT instruction affects the Z (Zero), S (Sign), and V
(Overflow) flags. The WDTMR must be written to within 64
internal system clocks. After that, the WDTMR is write pro-
tected.
Note:
WDT time-out while in Stop-Mode will not reset
SMR, PCON, WDTMR, P2M, P3M, Ports 2 and 3 Data
Registers, but will cause the reset delay to occur.
The Power-On Reset (POR) clock source is selected with
bit 4 of the WDTMR. Bits 0 and 1 control a tap circuit that
determines the time-out period. Bit 2 determines whether
the WDT is active during HALT and bit 3 determines WDT
activity during STOP. If bits 3 and 4 of this register are both
set to "1," the WDT is only driven by the external clock dur-
ing STOP Mode. This feature makes it possible to wake up
from STOP Mode from an internal source. Bits 5 through 7
of the WDTMR are reserved (Figure 39). This register is
accessible only during the first 60 processor cycles (60
SCLKs) from the execution of the first instruction after
Power-On-Reset, Watch-Dog Reset or a Stop-Mode Re-
covery. After this point, the register cannot be modified by
any means, intentional or otherwise. The WDTMR cannot
be read and is located in Bank F of the Expanded Register
group at address location 0FH.
