CHAPTER 16 DMA CONTROLLER (DMAC)
If only reloading of the transfer source/transfer destination register is enabled, restart after transfer is
performed the specified number of times is not implemented and only the values of each address register
are set.
[Special examples of operating mode and the reload operation]
If transfer is performed in continuous transfer mode by external pin input level detection and transfer
count register reloading is used, transfer continues by reloading even though transfer ends during
continuous input. Also in this case, an end code is set.
If it is preferable that processing stops when data transfer ends and starts after input is detected again,
do not specify reload.
For a transfer in burst, block, or step transfer mode, transfer stops temporarily after reload when data
transfer ends. Transfer does not start until new transfer request input is detected.
