14.4.2 Transfer mode
register.
interface, data resulting from A/D conversion can be consecutively transferred, and port data can be scanned at fixed
time intervals by using a timer.
14.4.3 Termination of DMA transfer
(INTDMAn) is generated and transfer is terminated.
when transfer is terminated.
DRSn
The following four modes can be selected for DMA transfer by using bits 6 and 5 (DRSn and DSn) of the DMCn
By using these transfer modes, up to 1024 bytes of data can be consecutively transferred by using the serial
When DBCn = 00H and DMA transfer is completed, the DSTn bit is automatically cleared to 0. An interrupt request
When the DSTn bit is cleared to 0 to forcibly terminate DMA transfer, the DBCn and DRAn registers hold the value
The interrupt request (INTDMAn) is not generated if transfer is forcibly terminated.
