Data transfer is initiated each time a DMA request is generated when the

• When the DMAE bit is set to “0” (disabled)
• After the DMAi transfer counter underflows
When a data transfer is started after setting the DMAE bit to “1” (en
abled), the forward address pointer is reloaded with the value of the
SARi or the DARi pointer whichever is specified to be in the forward
direction and the DMAi transfer counter is reloaded with the value of the
DMAi transfer counter reload register.
