TABLE 3-9 PORTE FUNCTIONS

Name

Bit# Buffer Type

Function

RE0/RD/AN5

RE1/WR/AN6

RE2/CS/AN7

bit0

ST/TTL(1) Input/output port pin or read control input in parallel slave port mode or

analog input:

RD

1 = Not a read operation

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

bit1

ST/TTL(1) Input/output port pin or write control input in parallel slave port mode or

analog input:

WR

1 = Not a write operation

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

bit2

ST/TTL(1) Input/output port pin or chip select control input in parallel slave port

mode or analog input:

CS

1 = Device is not selected

0 = Device is selected

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.
