PORTE FUNCTIONS
TABLE 9-10:
SUMMARY OF REGISTERS ASSOCIATED WITH PORTE
Name
Bit#
Buffer Type
Function
RE0/RD/AN5
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).
RE1/WR/AN6
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).
RE2/CS/AN7
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.
