The WDT has the following registers.
Table 14.2 Register Configuration
Note:
14.3.1
WTCNT is an 8-bit readable/writable register that is incremented by cycles of the selected clock
signal. When an overflow occurs, it generates a watchdog timer overflow signal (WDTOVF) in
watchdog timer mode and an interrupt in interval timer mode. WTCNT is initialized to H'00 by a
power-on reset caused by the RES pin or in deep standby mode or software standby mode.
Use word access to write to WTCNT, writing H'5A in the upper byte. Use byte access to read
from WTCNT.
Note: The method for writing to WTCNT differs from that for other registers to prevent
