1. Parallel Port

The MB90660A includes 39 I/O pins, 4 input pins, and 8 open-drain output pins.

Port 0, 1, 2, 3 and 6 are I/O ports. They are used for input when the corresponding direction register value is

“0”, and for output when the value is “1”.

Port 5 is an open-drain port. It is used as a port when the analog input enable register is “0”.

Ports 40 to 43 are I/O ports. They are used for input when the corresponding direction register value is “0”, and

for output when the value is “1”. Ports 44 to 47 are input ports which can only be used for reading data.
