Input/output port pin or address bit 16 for external memory interface.
Input/output port pin or address bit 17 for external memory interface.
Input/output port pin or address bit 18 for external memory interface.
Input/output port pin or address bit 19 for external memory interface.
Input/output port pin, analog input channel 12 or Enhanced PWM
output P3C.
Input/output port pin, analog input channel 13 or Enhanced PWM
output P3B.
Input/output port pin, analog input channel 14 or Enhanced PWM
output P1C.
Input/output port pin, analog input channel 15 or Enhanced PWM3
output P1B.
Legend: ST = Schmitt Trigger input, TTL = TTL input
Note 1: Input buffers are Schmitt Triggers when in I/O mode and TTL buffers when in System Bus or Parallel Slave
Port mode.
2: Valid only for PIC18F8525/8621 devices when ECCPMX is not set. The alternate assignments for
P1B/P1C/P3B/P3C in all PIC18F6525/6621 devices and in PIC18F8525/8621 devices when ECCPMX is
set are RE6, RE5, RE4 and RE3, respectively.
