Section 8 EXDMA Controller (EXDMAC)
8.3.3
EDTCR specifies the number of transfers. The function differs according to the transfer mode. Do
not write to EDTCR for a channel on which EXDMA transfer is in progress.

These bits are always read as 0 and cannot be
modified.
24-Bit Transfer Counter
These bits specify the number of transfers. Setting
H'000001 specifies one transfer. Setting H'000000
means no specification for the number of
transfers, and the transfer counter function is
halted. In this case, there is no transfer end
interrupt by the transfer counter. Setting
H'FFFFFF specifies the maximum number of
transfers, that is 16,777,215. During EXDMA
transfer, this counter shows the remaining number
of transfers.
This counter can be read at all times. When
reading EDTCR for a channel on which EXDMA
transfer processing is in progress, a longword-size
read must be executed.
