Section 11 10-Bit PWM
11.2.2
PWDRUm and PWDRLm form a 10-bit write-only register, with the upper 2 bits assigned to
PWDRUm and the lower 8 bits to PWDRLm. The value written to PWDRUm and PWDRLm
gives the total high-level width of one PWM waveform cycle.
When 10-bit data is written to PWDRUm and PWDRLm, the register contents are latched in the
PWM waveform generator, updating the PWM waveform generation data. The 10-bit data should
always be written in the following sequence:
1. Write the lower 8 bits to PWDRLm.
2. Write the upper 2 bits to PWDRUm for the same channel.
PWDRUm and PWDRLm are write-only registers. If they are read, all bits are read as 1.
Upon reset, PWDRUm is initialized to H'FC, and PWDRLm to H'00.
