60 64 52 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.

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
11 12
3 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

In microprocessor or extended microcontroller mode,
RE1 is the Output Enable (OE) control output (active
low).
RE2/WR

5 I/O TTL
In microprocessor or extended microcontroller mode,
RE2 is the Write Enable (WR) control output (active
low).

RF0 can also be analog input 4.
RF1/AN5
25 27 17 I/O ST
RF1 can also be analog input 5.
RF2/AN6
24 26 16 I/O ST
RF2 can also be analog input 6.
RF3/AN7
23 25 15 I/O ST
RF3 can also be analog input 7.
RF4/AN8

20 22 12 I/O ST
RF6 can also be analog input 10.
RF7/AN11
19 21 11 I/O ST
RF7 can slso be analog input 11.
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.
