8.4.11
Auto Request/Cycle Steal Mode/Normal Transfer Mode: When the EDA bit is set to 1 in
EDMDR, an EXDMA transfer cycle is started a minimum of three cycles later. There is a one-
cycle bus release interval between the end of a one-transfer-unit EXDMA cycle and the start of the
next transfer.
If there is a transfer request for another channel of higher priority, the transfer request by the
original channel is held pending, and transfer is performed on the higher-priority channel from the
next transfer. Transfer on the original channel is resumed on completion of the higher-priority
channel transfer.
Figures 8.28 to 8.30 show operation timing examples for various conditions.
