14.4 PWM Cycle Setting Register (PCSR)
The PWM cycle setting register (PCSR) is used to set a cycle. This register has a
buffer. A borrow occurring in the counter triggers a transfer from the buffer.
■ PWM Cycle Setting Register (PCSR)
The configuration of the PWM cycle setting register (PCSR) is shown below.
After the cycle setting register is initialized or rewritten, write to the duty cycle setting register.
Use a 16-bit data instruction to access the cycle setting register.
