Section 19 Motor Control PWM Timer
19.2.6
There are four PWDTR1x registers (PWDTR1A, 1C, 1E, 1G). PWDTR1A is used for outputs
PWM1A and PWM1B, PWDTR1C for outputs PWM1C and PWM1D, PWDTR1E for outputs
PWM1E and PWM1F, and PWDTR1G for outputs PWM1G and PWM1H.
PWDTR1 cannot be read or written to directly. When a PWCYR1 compare match occurs, data is
transferred from buffer register 1 (PWBFR1) to PWDTR1.
PWDTR1x is initialized to H'EC00 when the counter start bit (CST) in PWCR1 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
Bits 15 to 13—Reserved: These bits cannot be read from or written to.
