TABLE 10-9: 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.

For RD (PSP Control mode):

1 = PSP is Idle

0 = Read operation. Reads PORTD register (if chip selected).

RE1/AN6/WR

bit 1

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

Slave Port mode.

For WR (PSP Control mode):

1 = PSP is Idle

0 = Write operation. Writes PORTD register (if chip selected).

RE2/AN7/CS

bit 2

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

Slave Port mode.

For CS (PSP Control mode):

1 = PSP is Idle

0 = External device is selected

MCLR/VPP/RE3 bit 3

ST

Input only port pin or programming voltage input (if MCLR is disabled);

Master Clear input or programming voltage input (if MCLR is enabled).

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.
