Interrupt on completion of transfer. Determines whether an interrupt is generated by completing a
transfer or by the occurrence of an error condition.
0 No interrupt is generated.
1 Internal interrupt signal is enabled.
Enable external request. Care should be taken because a collision can occur between the START bit
and DREQ when EEXT = 1.

Auto-align. AA and SIZE determine whether the source or destination is auto-aligned, that is,

destination accesses are auto-aligned. Source alignment takes precedence over destination
alignment. If auto-alignment is enabled, the appropriate address register increments, regardless
