13.9 I/O Signals
13.10 I/O Registers
13.10.1 PWM Control Register (PWMCR)
MC68HC908SR12•MC68HC08SR12 — Rev. 5.0
Freescale Semiconductor
Address:
The PWM module has three output pins shared with port C:
PTC0/PWM0/CD, PWM1/PTC1, and PTC2/PWM2. PTC0 is also shared
with current flow detect output, CD, of the analog module, see (see 18.5
Port C).
These I/O registers control PWM operation:
The PWM control register (PWMCR) enables/disables the independent
PWM counters and port pins used for the PWM channels.
PWMEN2–PWMEN0 — PWM Enable Bits

Writing a 0 to the PWMENx bit clears the corresponding PWM counter
and force the PWM channel x output to 0. Reset clears these bits.
1 = PWM channel x enabled
0 = PWM channel x is disabled; PWM counter cleared to zero and
