Bit
Initial value
Read/Write
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.
Note: * Subclock functions (subactive mode, subsleep mode, and watch mode) are available in the

U-mask and W-mask versions, and H8S/2635 Group only.
These functions cannot be used with the other versions.
