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.
