PWCNT is a 10-bit up-counter incremented by the input clock. The input clock is selected by
clock select bits 2 to 0 (CKS2 to CKS0) in PWCR.
PWCNT1 is used as the channel 1 time base, and PWCNT2 as the channel 2 time base.
PWCNT is initialized to H'FC00 when the counter start bit (CST) in PWCR is cleared to 0, and
also upon reset and in standby mode, watch mode, subactive mode, subsleep mode, and module
stop mode.
