PORTE FUNCTIONS
TABLE 10-10: SUMMARY OF REGISTERS ASSOCIATED WITH PORTE
Name
Bit#
Buffer Type
Function
RE0/AN5/RD
bit 0
ST/TTL(1)
Input/output port pin, analog input or read control input in Parallel Slave
Port mode.
For RD (PSP Control mode):
1 = PSP is Idle
0 = Read operation. Reads PORTD register (if chip selected).
RE1/AN6/WR
bit 1
ST/TTL(1)
Input/output port pin, analog input or write control input in Parallel
Slave Port mode.
For WR (PSP Control mode):
1 = PSP is Idle
0 = Write operation. Writes PORTD register (if chip selected).
RE2/AN7/CS
bit 2
ST/TTL(1)
Input/output port pin, analog input or chip select control input in Parallel
Slave Port mode.
For CS (PSP Control mode):
1 = PSP is Idle
0 = External device is selected
MCLR/VPP/RE3(2)
bit 3
ST
Input only port pin or programming voltage input (if MCLR is disabled);
Master Clear input or programming voltage input (if MCLR is enabled).
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.
2: The RE3 port bit is available as an input-only pin only in 40-pin devices and when Master Clear function-
ality is disabled (CONFIG3H<7>=0).

Shaded cells are not used by PORTE.
Note 1:
The RE3 port bit is available as an input-only pin only in 40-pin devices and when Master Clear functionality is disabled
(CONFIG3H<7>=0).
