HARDWARE ACTIVATED DIGITAL WATCHDOG FUNCTION (Cont’d)
Hardware Activated Watchdog Register
(HWDR)
Address: D8h - Read/Write
Reset Value: 0FEh
T1-T6. These are the watchdog counter bits. It
should be noted that D7 (T1) is the LSB of the
counter and D2 (T6) is the MSB of the counter,
these bits are in the opposite order to normal.
SR. This bit is set to one during the reset phase
and will generate a software reset if cleared to ze-
ro.
C. This is the watchdog activation bit that is hard-
ware set. The watchdog function is always activat-
ed independently of changes of value of this bit.
The register reset value is FEh (Bit 1-7 set to one,
Bit 0 cleared).
