TABLE 5-9: PORTE FUNCTIONS
TABLE 5-10: 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.
