• OC.3A/OC.4A – Port C, Bit 6
OC.3A: Timer 3 Output Compare A. This pin can be used to generate a PWM signal from Timer
3 module.
OC.4A: Timer 4 Output Compare A. This pin can be used to generate a high-speed PWM signal
from Timer 4 module, complementary to OC.4A (PC7) signal. The pin has to be configured as an
output (DDC6 set “one”) to serve this function.
