TABLE 9-9: PORTE FUNCTIONS
Name
Bit# Buffer Type
Function
RE0/AN5/RD
bit0
ST/TTL⁽¹⁾
Input/output port pin or analog input or read control input in Parallel
Slave Port mode
For RD (PSP mode):
1 = Not a read operation
0 = Read operation. Reads PORTD register (if chip selected).
RE1/AN6/WR bit1
ST/TTL⁽¹⁾
Input/output port pin or analog input or write control input in Parallel
Slave Port mode
For WR (PSP mode):
1 = Not a write operation
0 = Write operation. Writes PORTD register (if chip selected).
RE2/AN7/CS
bit2
ST/TTL⁽¹⁾
Input/output port pin or analog input or chip select control input in
Parallel Slave Port mode
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.
