TABLE 10-9: PORTE FUNCTIONS
TABLE 10-10: SUMMARY OF REGISTERS ASSOCIATED WITH PORTE
Name Bit# Buffer Type Function
RE0/RD/AD8 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 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 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 bit 3 ST/TTL
(1)
Input/output port pin or address/data bit 11.
RE4/AD12 bit 4 ST/TTL
(1)
Input/output port pin or address/data bit 12.
RE5/AD13 bit 5 ST/TTL
(1)
Input/output port pin or address/data bit 13.
RE6/AD14 bit 6 ST/TTL
(1)
Input/output port pin or address/data bit 14.
RE7/CCP2/AD15 bit 7 ST/TTL
(1)
Input/output port pin, Capture2 input/Compare2 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.
