DS80CH11
BIT 0
Read/Write Access: Unrestricted.
Initialization: 00H on any type of reset
Used to access the PWM n timer and the PWM n
compare values that selects the PWM duty cycle. This
register provides read/write access to both. The selec-
tion of the active function is controlled by the PWnT/C
bit. When PWnT/C = 0, then PWM n register accesses
the PWM compare value. Writing a new value to PWM n
will then select a new duty cycle. The new value will be
loaded from the register into the PWM comparator when
the timer reaches the previous PWM compare value.
When PWnT/C = 1, the register accesses the PWM n
timer value. This allows software to monitor the prog-
ress through the duty cycle or to use PWM channel n as
an 8–bit timer.
