17.3 Register Descriptions
The 14-bit PWM has the following registers.
• PWM1 control register (PWCR1)
• PWM1 data register (PWDR1)
• PWM2 control register (PWCR2)
• PWM2 data register (PWDR2)
17.3.1 PWM Control Register (PWCR)
PWCR selects the input clocks and selects whether the standard PWM or pulse-division type
PWM is used.
