PIN NAME
FUNCTION
11 Port 1
12 Port 2
Input pins (input ports) for peripheral IC control
signals (digital signals).
Apply (supply) to this pin output returned from
peripheral ICs which are controlled by
microcontroller via this IC. The return output
contains data on operating status of peripheral ICs
controlled by microcontroller (eg, operating status
and operating mode set by microcontroller).
