14.5 PWM Duty Cycle Setting Register (PDUT)
The PWM duty cycle setting register (PDUT) is used to set a duty cycle. This register
has a buffer. A borrow occurring in the counter triggers a transfer from the buffer.
PWM Duty Cycle Setting Register (PDUT)
The configuration of the PWM duty cycle setting register (PDUT) is shown below.
PDUT
Address: ch0 0000E4
ch1 0000EC
ch2 0000F4
ch3 0000FC
Attribute
Initial value
When the same value is set in the cycle setting register and duty cycle setting register, output is
kept at a high level in normal polarity mode or output is kept at a low level in inverse polarity
mode.
To ensure stable PWM output, set values that make PCSR smaller than PDUT.
Use a 16-bit data instruction to access the cycle setting register.
