SUMMARY OF REGISTERS ASSOCIATED WITH PORTE
Name
Bit#
Buffer Type
Function
RE0/RD/AN5
bit 0
ST/TTL(1)
Input/output port pin or read control input in Parallel Slave Port mode or
analog input.
For RD (PSP mode):
1
= Idle
0
= Read operation. Contents of PORTD register output to PORTD I/O
pins (if chip selected).
RE1/WR/AN6
bit 1
ST/TTL(1)
Input/output port pin or write control input in Parallel Slave Port mode
or analog input.
For WR (PSP mode):
1
=Idle
0
= Write operation. Value of PORTD I/O pins latched into PORTD
register (if chip selected).
RE2/CS/AN7
bit 2
ST/TTL(1)
Input/output port pin or Chip Select control input in Parallel Slave Port
mode or analog input.
For CS (PSP mode):
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.
