Figure 8.2 illustrates how I/O mode operates.
The transfer count is specified as a 16-bit value in ETCR. The ETCR value is decremented by 1 at
each transfer. When the ETCR value reaches H'0000, the DTE bit is cleared and the transfer ends.
If the DTIE bit is set to 1, a CPU interrupt is requested at this time. The maximum transfer count
is 65,536, obtained by setting ETCR to H'0000.
Transfers can be requested (activated) by compare match/input capture A interrupts from ITU
channels 0 to 3, transmit-data-empty and receive-data-full interrupts from SCI channel 0, and
external request signals.
