TABLE 5-11: PORTE FUNCTIONS
TABLE 5-12: SUMMARY OF REGISTERS ASSOCIATED WITH PORTE
Name Bit# Buffer Type Function
RE0/RD
bit0 ST/TTL
(1)
Input/output port pin or Read control input in parallel slave port mode.
RD
1 = Not a read operation
0 = Read operation. The system reads the PORTD register (if
chip selected)
RE1/WR
bit1 ST/TTL
(1)
Input/output port pin or Write control input in parallel slave port mode.
WR
1 = Not a write operation
0 = Write operation. The system writes to the PORTD register (if
chip selected)
RE2/CS
bit2 ST/TTL
(1)
Input/output port pin or Chip select control input in parallel slave port
mode.
CS
1 = Device is not selected
0 = Device is selected
Legend: ST = Schmitt Trigger input, TTL = TTL input
Note 1: Buffer is a Schmitt Trigger when in I/O mode, and a TTL buffer when in Parallel Slave Port (PSP) mode.
