■ P26: The functions of Port 26 are controlled by PFR26 and EPFR26
P26[7:0] is input/output for Stepper Motor PWM output signals and Comparator Inputs SMC2M, SMC2P,
SMC1M, SMC1P of channels 2 and 3, and A/D converter analogue inputs AN[31:24]. Otherwise, the port can be
used as general purpose port.
