15.3
The WDT has the following three registers. To prevent accidental overwriting, TCSR, TCNT, and
RSTCSR have to be written to in a method different from normal registers. For details, see section
15.6.1, Notes on Register Access.
• Timer counter (TCNT)
• Timer control/status register (TCSR)
• Reset control/status register (RSTCSR)
15.3.1
TCNT is an 8-bit readable/writable up-counter. TCNT is initialized to H'00 when the TME bit in
TCSR is cleared to 0.
15.3.2
TCSR selects the clock source to be input to TCNT, and the timer mode.
