TABLE 10-9: PORTE FUNCTIONS
TABLE 10-10: SUMMARY OF REGISTERS ASSOCIATED WITH PORTE
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)
RE2/CS
/AD10
(2)
bit 2 ST/TTL
(1)
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
RE3/AD11
(2)
bit 3 ST/TTL
(1)
Input/output port pin or address/data bit 11.
RE4/AD12
(2)
bit 4 ST/TTL
(1)
Input/output port pin or address/data bit 12.
RE5/AD13/
(2)
P1C
(3)
bit 5 ST/TTL
(1)
Input/output port pin, address/data bit 13 or ECCP1 PWM output C.
RE6/AD14/
(2)
P1B
(3)
bit 6 ST/TTL
(1)
Input/output port pin, address/data bit 13 or ECCP1 PWM output B.
RE7/CCP2/AD15
(2)
bit 7 ST/TTL
(1)
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.
