TABLE 9-9: PORTE FUNCTIONS

Name

Bit# Buffer Type

Function

RE0/AN5/RD

bit 0 ST/TTL(1) Input/output port pin, analog input or read control input in Parallel

Slave Port mode.

RE1/AN6/WR/C1OUT bit 1

ST/TTL(1) Input/output port pin, analog input, write control input in Parallel Slave

Port mode or Comparator 1 output.

RE2/AN7/CS/C2OUT bit 2

ST/TTL(1) Input/output port pin, analog input, chip select control input in Parallel

Slave Port mode or Comparator 2 output.

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 Parallel Slave Port mode.
