CXP750064/750072/750080
(Port A)
8-bit I/O port.
I/O can be set in a
unit of single bits.
(8 pins)
(Port B)
8-bit I/O port. I/O can be set in a unit of single bits.
(8 pins)
(Port C)
Lower 6 bits are I/O ports; I/O can be set in a unit of single bits. Upper
2 bits are output port and large current (12mA) N-channel open drain
output. Upper 2 bits are medium drive voltage (12V); lower 6 bits are
5V drive.
(8 pins)
8-bit PWM output.
(2 pins)
(Port D)
8-bit I/O port. I/O
can be set in a
unit of single bits.
Can drive 12mA
synk current.
(8 pins)
(Port E)
Bits 0 and 1 are I/O
port; I/O can be set
in a unit of single.
Bits 2 and 3 are
input port. Bits 4, 5
and 6 are output
port.
