CXP82220/82224
Pin Description
– 4 –
(Port A)
8-bit I/O port. I/O can be
set in a unit of single bit .
(8 pins)
(Port B)
8-bit I/O port. I/O for lower
7 bits can be set in a unit
of single bit. Uppermost
bit (PB7) is for output only.
(8 pins)
(Port C)
8-bit I/O port. I/O can be
set in a unit of single bits.
Capable of driving 12mA
synk current. (8 pins)
(Port D)
(8 pins)
(Port E)
8-bit port. Lower 6 bits are
for inputs; upper 2 bits are
for outputs.
(8 pins)
(Port F)
8-bit output port.
(8 pins)
(Port G)
8-bit I/O port. I/O can be
set in a unit of single bit.
