8.8 Serial Interface
Three independent serial interface channels are incorporated.
Asynchronous serial interface (UART)/three-wire serial I/O (IOE)
×
2
Synchronous serial interface (CSI)
×
1
Three-wire serial I/O (IOE)
Two-wire serial I/O (IOE)
So, communication with points external to the system and local communication within the system can be performed
at the same time. (See
Figure 8-9
.)
