TABLE 10-9: PORTE FUNCTIONS
Name
Bit# Buffer Type
Function
RE0/RD/AD8⁽²⁾
bit 0 ST/TTL⁽¹⁾ Input/output port pin, read control for Parallel Slave Port or
address/data bit 8.
For RD (PSP Control mode):
1 = Not a read operation
0 = Read operation, reads PORTD register (if chip selected)
RE1/WR/AD9⁽²⁾
bit 1 ST/TTL⁽¹⁾ Input/output port pin, write control for Parallel Slave Port or
address/data bit 9.
For WR (PSP Control mode):
1 = Not a write operation
0 = Write operation, writes PORTD register (if chip selected)

Input/output port pin, chip select control for Parallel Slave Port or
address/data bit 10.
For CS (PSP Control mode):
1 = Device is not selected
0 = Device is selected
Input/output port pin or address/data bit 11.
Input/output port pin or address/data bit 12.
Input/output port pin, address/data bit 13 or ECCP1 PWM output C.
Input/output port pin, address/data bit 13 or ECCP1 PWM output B.
Input/output port pin, Capture 2 input/Compare 2 output/PWM output
(PIC18F8X20 devices in Microcontroller mode only) or
address/data bit 15.
Legend: ST = Schmitt Trigger input, TTL = TTL input
Note 1: Input buffers are Schmitt Triggers when in I/O or CCP mode, and TTL buffers when in System Bus or PSP
Control mode.
2: Available in PIC18F8X8X devices only.
3: On PIC18F8X8X devices, these pins may be moved to RHY or RH6 by changing the ECCPMX
configuration bit.
