4.2.
PWM1 and PWM2 Compare Registers (PWC1, PWC2)
The value of the 8/10 bit PWM1 and PWM2 Compare Registers determines the width of the PWM pulse.
A value of 0x00 (0x000) indicates that the PWM duty cycle is 0%, while a value of 0xFF (0x3FF) indicates
that the PWM duty cycle is 99.6% (99.9%).

[bit9:0] D[9:0]: PWM1 Compare Data Value
The PWM1 Compare Data Value D[9:0] are used to set the PWM1 duty cycle. When the Operation Mode
Switching bit is set to 8-bit operation mode (PWC.SC= "0"), the compare data value is taken from D[7:0]
bits and D[9:8] bits are "don't care". When the Operation Mode Switching bit is set to 10-bit operation
mode (PWC.SC= "1"), the compare data value is taken from D[9:0] bits.
