TABLE 9-9: PORTE FUNCTIONS
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.
