Watch-Dog Timer.
The Watch-Dog Timer is activated au-
tomatically 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
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
.
WDT During HALT (D5-R250).
This bit determines wheth-
er or not the WDT is active during HALT Mode. The default
is 1, and a 1 indicates active during HALT.
