Preliminary

PORTC is a bi-directional I/O Port.

RC0/AD0

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 con-

ﬁguration, these pins are address output as well as

data input or output.

PORTD is a bi-directional I/O Port.

RD0/AD8

I/O

TTL

This is also the most signiﬁcant byte (MSB) of the

16-bit system bus in microprocessor mode or extended

microprocessor mode or extended microcontroller

mode. In multiplexed system bus conﬁguration these

pins are address output as well as data input or output.

PORTE is a bi-directional I/O Port.

RE0/ALE

I/O

TTL

In microprocessor mode or extended microcontroller

mode, RE0 is the Address Latch Enable (ALE) output.

Address should be latched on the falling edge of ALE

output.

RE1/OE

I/O

TTL

In microprocessor or extended microcontroller mode,

RE1 is the Output Enable (OE) control output (active

low).

RE2/WR

I/O

TTL

In microprocessor or extended microcontroller mode,

RE2 is the Write Enable (WR) control output (active

low).

RE3/CAP4

I/O

RE3 can also be the Capture4 input pin.

PORTF is a bi-directional I/O Port.

RF0/AN4

I/O

RF0 can also be analog input 4.

RF1/AN5

I/O

RF1 can also be analog input 5.

RF2/AN6

I/O

RF2 can also be analog input 6.

RF3/AN7

I/O

RF3 can also be analog input 7.

RF4/AN8

I/O

RF4 can also be analog input 8.

RF5/AN9

I/O

RF5 can also be analog input 9.

RF6/AN10

I/O

RF6 can also be analog input 10.

RF7/AN11

I/O

RF7 can slso be analog input 11.

Type Description

Legend: I = Input only; O = Output only; I/O = Input/Output; P = Power; — = Not Used; TTL = TTL input;

ST = Schmitt Trigger input.

†

The output is only available by the Peripheral operation.
