The bi-directional Port 4 is a bit-wise configurable I/O port and provides the external pins for the
Timer 2, SSI and the voltage monitor input (VMI). As a normal port, it performs in exactly the
same way as bi-directional Port 2 (see
port direction control to be passed over to other internal modules (Timer 2, VM or SSI). The I/O
pins for the SC and SD lines have an additional mode to generate an SSI-interrupt.
All four Port 4 pins can be individually switched by the P4CR register.
