Chapter 10 Ports (INPUT, OUTPUT, I/O PORT)
10.1 Overview
The ML63326 has one internal 4-bit input port, four internal 4-bit output ports, five internal 4-
bit I/O ports, and one internal 2-bit I/O port.
The V
DDI
(interface power supply) pin supplies power to the ports.
If a port is to be connected to an external device that operates on a different power supply,
the power supply of the external device must be fed to the V
DDI
pin.
!
Note:
Since V
DDI
is separated from the positive power supply pin (V
DD
), power must be supplied
to the V
DDI
pin.
