(3) Watchdog timer mode register (WDTM)
Notes 1. Once the RUN bit is set (to 1), it cannot be cleared (to 0) by software.
This register sets the watchdog timer operation mode and enables/disables count operations.
This register is a special register that can be written only in a special sequence (refer to 3.4.8 Special
registers).
The WDTM register can be read or written in 8-bit or 1-bit units.
This register is cleared to 00H after reset.
2. Once the WDTM3 and WDTM4 bits are set (to 1), they cannot be cleared (to 0) by software and can
Therefore, when counting is started, it cannot be stopped except by reset (RESET input or watchdog
timer overflow).
