The WDT has the following three registers. To prevent accidental overwriting, TCSR, TCNT, and
RSTCSR have to be written to by a different method to normal registers. For details, refer to
section 13.6.1, Notes on Register Access. For details on the system control register and pin
function control register, refer to section 3.2.2, System Control Register (SYSCR) and section
7.3.6, Pin Function Control Register (PFCR), respectively.
• Timer counter (TCNT)
• Timer control/status register (TCSR)
• Reset control/status register (RSTCSR)
