Bit 0 Clock Select 0 (PWCR0): Bit 0 selects the clock supplied to the 14-bit PWM. This bit is a
write-only bit; it is always read as 1.

PWDRU
PWDRL
PWDRU and PWDRL form a 14-bit write-only register, with the upper 6 bits assigned to PWDRU
and the lower 8 bits to PWDRL. The value written to PWDRU and PWDRL gives the total high-
level width of one PWM waveform cycle.
When 14-bit data is written to PWDRU and PWDRL, the register contents are latched in the PWM
waveform generator, updating the PWM waveform generation data. The 14-bit data should always
be written in the following sequence:
1. Write the lower 8 bits to PWDRL.
2.
PWDRU and PWDRL are write-only registers. If they are read, all bits are read as 1.
