Section 8 EXDMA Controller (EXDMAC)
(2)
When the EDA bit is set to 1 in EDMDR, an EXDMA transfer cycle is started a minimum of three
cycles later. Once transfer is started, it continues (as a burst) until the transfer end condition is
satisfied.
If the BGUP bit is 1 in EDMDR, the bus is transferred in the event of a bus request from another
bus master.
Transfer requests for other channels are held pending until the end of transfer on the current
channel.
Figures 8.31 to 8.34 show operation timing examples for various conditions.
