I/O

Description

(Port F)

Lower 4 bits are for inputs; upper 4 bits are for

outputs. Lower 4 bits also serve as standby

release input pins.

(8 pins)

(Port H)

8-bit I/O port. Upper four

bits are for outputs. I/O

can be set in a unit of

single bits for lower four

bits.

Lower four bits are N-ch open drain outputs and which can drive 12mA

sink current.

Upper four bits are for outputs; N-ch open drain output of medium drive

voltage (12V) and large current (12mA).
