Description
PORTD is a bi-directional I/O Port.
PORTE is a bi-directional I/O Port.
mal operation.
Ground reference for logic and I/O pins.
Test mode selection control input. Always tie to V
Positive supply for logic and I/O pins.
This is also the upper byte 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.
In microprocessor mode or extended microcontroller
mode, it is the Address Latch Enable (ALE) output.
Address should be latched on the falling edge of ALE
output.
In microprocessor or extended microcontroller mode, it is
the Output Enable (OE) control output (active low).
In microprocessor or extended microcontroller mode, it is
the Write Enable (WR) control output (active low).
