Therefore, always initialize mailboxes after a power-on reset, a
transition to hardware standby mode, software standby mode,
module stop mode, or watch mode. After a power-on reset,
recovery from software standby mode, or cancellation of
module stop mode, the reset interrupt flag (IRR0) is
automatically set.

Activation: Setting the CST bit in PWCR to 1 starts counting by
PWCNT. When a compare match between PWCNT and
PWCYR occurs, data is transferred from the buffer register to
the duty register and the CMF bit in PWCR is set to 1. If the IE
bit in PWCR has been set to 1 at this time, an interrupt can be
requested or the DTC can be activated.
