Transmission
In the group 0 communication function, clock synchronous mode or HDLC data processing mode is available. In
the group 1 communication function, clock synchronous mode, clock asynchronous (UART) mode, or HDLC data
processing mode is available. Figure 22.36 shows a block diagram of group 0 communication function. Figure
22.37 shows a block diagram of group 1 communication function. Figures 22.38 to 22.46 show registers associated
with the communication function.
