I/O

I/O ports in CMOS. Each port can be programmed to

input or output under the control of the direction register.

Pull-up resistors are selected for following 4-pin units, but

are enabled only for the input pins: Pi_0 to Pi_3 and Pi_4

to Pi_7 (i = 0 to 15)

Input port

P14_1

Input port in CMOS. Pull-up resistors are selectable for

P14_1 and P14_3
