Note: * Only 0 can be written, to clear the flag.
PWCR is an 8-bit read/write register that performs interrupt enabling, starting/stopping, and
counter (PWCNT) clock selection. It also contains a flag that indicates a compare match with the
cycle register (PWCYR). PWCR1 is the channel 1 register, and PWCR2 is the channel 2 register.
PWCR is initialized to H'C0 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
Bits 7 and 6—Reserved: They are always read as 1 and cannot be modified.
Bit 5—Interrupt Enable (IE): Bit 5 selects enabling or disabling of an interrupt in the event of a
compare match with the PWCYR register for the corresponding channel.
