by IOAR. The transfer direction can be specified by the DTDIR bit in DMACR. Table 7.6
summarizes register functions in idle mode.
Table 7.6
MAR specifies the start address of the transfer source or transfer destination as 24 bits. MAR is
neither incremented nor decremented by a data transfer. IOAR specifies the lower 16 bits of the
other address. The upper 8 bits of IOAR have a value of H'FF.
Figure 7.5 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 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 external requests, SCI transmission complete and
reception complete interrupts, and TPU channel 0 to 5 compare match/input capture A interrupts.
