Initial value
Read/Write
PWCYR is a 16-bit read/write register that sets the PWM conversion cycle. When a PWCYR
compare match occurs, PWCNT is cleared and data is transferred from the buffer register
(PWBFR) to the duty register (PWDTR). PWCYR1 is used for the channel 1 conversion cycle
setting, and PWCYR2 for the channel 2 conversion cycle setting.
PWCYR should be written to only while PWCNT is stopped. A value of H'FC00 must not be set.
PWCYR is initialized to H'FFFF 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
