Pulse Width Modulator (PWM)
13.10.2 PWM Clock Control Register (PWMCCR)
Data Sheet
218
Address:
PCH2–PCH0 — PWM Channel Enable Bits
Exception for PTC0/PWM0/CD control:
The PWM clock control register (PWMCCR) selects and defines the
clock to the PWM counter, P
PCLKSEL — PWM Input Clock Select Bit
Reset:
Read:
Write:
Setting a bit will enable the corresponding port pin to be a PWM
output pin. When a bit is set, the DDR bit has no effect on the port
function.
This bit selects either the CGMOUT or CGMVCLK clock as the input
clock to the PWM counters. Reset clears this bit.
PTC0/PWM0/CD
1 = Port pin is enabled for PWM output
0 = Port pin is standard I/O pin
1 = Select CGMVCLK as PWM input clock
0 = Select CGMOUT (CPU bus clock) as PWM input clock
