11.2
The WDT has the pins listed in table 11.1.
Table 11.1 Pin Configuration
11.3
The WDT has the following registers. To prevent accidental overwriting, TCSR and TCNT have
to be written to in a method different from normal registers. For details, refer to section 11.6.1,
Notes on Register Access. For details on the system control register, refer to section 3.2.2, System
Control Register (SYSCR).
11.3.1
TCNT is an 8-bit readable/writable up-counter.
TCNT is initialized to H'00 when the TME bit in the timer control/status register (TCSR) is
cleared to 0.
