Port 4 is an I/O port with an output latch. Port 4 can be set to the input mode or output mode in 1-bit units using port
This port can also be used for external interrupt request input, real-time counter clock output, real-time counter
The clock I/O and data input of the serial interface can be assigned to P40 and P41 of the 78K0/KC2-L (44-pin and 48-
Reset signal generation sets port 4 to input mode.
Figures 4-19 to 4-21 show block diagrams of port 4.
