LC86E4448

Pin Description

• Port option can be specified by bit units.

• At port 0, 'Pull-up resistor provided' when specifying CMOS output.

'Pull-up resistor not provided' when specifying N-ch open drain output.

• At port 1 and 2, 'Programmable pull-up resistor provided' when specifying either CMOS or N-ch open drain output.
