PIC17C7XX
PORTC is a bi-directional I/O Port.
RC0/AD0 2 3 58 3 72 I/O TTL This is also the least significant byte (LSB) of
the 16-bit wide system bus in Microprocessor
mode or Extended Microcontroller mode. In
multiplexed system bus configuration, these
pins are address output as well as data input or
output.
RC1/AD1 63 67 55 83 69 I/O TTL
RC2/AD2 62 66 54 82 68 I/O TTL
RC3/AD3 61 65 53 81 67 I/O TTL
RC4/AD4 60 64 52 80 66 I/O TTL
RC5/AD5 58 63 51 79 65 I/O TTL
RC6/AD6 58 62 50 78 64 I/O TTL
RC7/AD7 57 61 49 77 63 I/O TTL
PORTD is a bi-directional I/O Port.
RD0/AD8 10 11 2 15 4 I/O TTL This is also the most significant byte (MSB) of
the 16-bit system bus in Microprocessor mode
or Extended Microcontroller mode. In multi-
plexed system bus configuration, these pins are
address output as well as data input or output.
RD1/AD9 9 10 1 14 3 I/O TTL
RD2/AD10 8 9 64 9 78 I/O TTL
RD3/AD11 7 8 63 8 77 I/O TTL
RD4/AD12 6 7 62 7 76 I/O TTL
RD5/AD13 5 6 61 6 75 I/O TTL
RD6/AD14 4 5 60 5 74 I/O TTL
RD7/AD15 3 4 59 4 73 I/O TTL
PORTE is a bi-directional I/O Port.
RE0/ALE 11 12 3 16 5 I/O TTL In Microprocessor mode or Extended Microcon-
troller mode, RE0 is the Address Latch Enable
(ALE) output. Address should be latched on the
falling edge of ALE output.
RE1/OE
12 13 4 17 6 I/O TTL In Microprocessor or Extended Microcontroller
mode, RE1 is the Output Enable (OE
) control
output (active low).
RE2/WR
13 14 5 18 7 I/O TTL In Microprocessor or Extended Microcontroller
mode, RE2 is the Write Enable (WR
) control
output (active low).
RE3/CAP4 14 15 6 19 8 I/O ST RE3 can also be the Capture4 input pin.
PORTF is a bi-directional I/O Port.
RF0/AN4 26 28 18 36 24 I/O ST RF0 can also be analog input 4.
RF1/AN5 25 27 17 35 23 I/O ST RF1 can also be analog input 5.
RF2/AN6 24 26 16 30 18 I/O ST RF2 can also be analog input 6.
RF3/AN7 23 25 15 29 17 I/O ST RF3 can also be analog input 7.
RF4/AN8 22 24 14 28 16 I/O ST RF4 can also be analog input 8.
RF5/AN9 21 23 13 27 15 I/O ST RF5 can also be analog input 9.
RF6/AN10 20 22 12 26 14 I/O ST RF6 can also be analog input 10.
RF7/AN11 19 21 11 25 13 I/O ST RF7 can also be analog input 11.
