Alternate Functions of Port L
Table 12-32. Overriding Signals for Alternate Functions in PK3:PK0
The Port L alternate pin configuration is as follows:
Table 12-33. Port L Pins Alternate Functions
• OC5C – Port L, Bit 5
OC5C, Output Compare Match C output: The PL5 pin can serve as an external output for the
Timer/Counter5 Output Compare C. The pin has to be configured as an output (DDL5 set) to
serve this function. The OC5C pin is also the output pin for the PWM mode timer function.
• OC5B – Port L, Bit 4
OC5B, Output Compare Match B output: The PL4 pin can serve as an external output for the
Timer/Counter 5 Output Compare B. The pin has to be configured as an output (DDL4 set) to
serve this function. The OC5B pin is also the output pin for the PWM mode timer function.
• OC5A – Port L, Bit 3
OC5A, Output Compare Match A output: The PL3 pin can serve as an external output for the
Timer/Counter 5 Output Compare A. The pin has to be configured as an output (DDL3 set) to
serve this function. The OC5A pin is also the output pin for the PWM mode timer function.
