The bi-directional Port 4 is a bitwise 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 Figure 32). Two additional multi-
plexes allow data and port direction control to be passed over to other internal modules
(Timer 2, VM or SSI). The I/O-pins for SC and SD line have an additional mode to
generate an SSI-interrupt.
All four Port 4 pins can be individually switched by the P4CR-register. Figure 32 shows
the internal interfaces to bi-directional Port 4.
