Figure 8.5 illustrates operation in idle mode.
The number of transfers is specified as 16 bits in ETCR. ETCR is decremented by 1 each time a
transfer is executed, and when its value reaches H'0000, the DTE bit in DMABCR in common
register enabled mode or the DTE bit in DMAECRS in common register disabled mode is cleared
and data transfer ends. If the DTIE bit is set to 1 at this time, an interrupt request is sent to the
CPU or DTC. The maximum number of transfers, when H'0000 is set in ETCR, is 65,536.
Transfer requests (activation sources) consist of A/D converter conversion end interrupts, external
requests, SCI transmit data empty and receive data full interrupts, and TPU channel 0 to 5
compare match/input capture A interrupts.
