(1) Watchdog timer mode register 2 (WDTM2)
Cautions 1. For details of the WDCS20 to WDCS24 bits, see Table 11-2 Watchdog Timer 2 Clock
Caution Accessing the WDTM2 register is prohibited in the following statuses. For details, see 3.4.8 (2)
The WDTM2 register sets the overflow time and operation clock of watchdog timer 2.
This register can be read or written in 8-bit units. This register can be read any number of times, but it can be
written only once following reset release.
Reset sets this register to 67H.
