x = unknown, u = unchanged, - = unimplemented, read as ‘0’, q = value depends on condition.
Shaded cells are not used by PORTE.
Implemented only when Master Clear functionality is disabled (CONFIG3H<7> = 0).
Input buffers are Schmitt Triggers when in I/O mode and TTL buffers when in Parallel Slave Port mode.

PIC18F2220/2320/4220/4320
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).
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).
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
Input only port pin or programming voltage input (if MCLR is disabled);
Master Clear input or programming voltage input (if MCLR is enabled).
