8.8 Serial Interface
Four independent serial interface channels are incorporated.
Asynchronous serial interface (UART)/3-wire serial I/O (IOE)
×

3-wire serial I/O (IOE)
This makes it possible for communication with an external system and local communication within the system to
be simultaneously executed (see
Figure 8-10
).
