Bit 4—Data Transfer Direction (DTDIR): Used in combination with the SAE bit in DMABCR to specify the data
transfer direction (source or destination). The function of this bit is therefore different in dual address mode and single
address mode.

Bits 3 to 0—Data Transfer Factor (DTF3 to DTF0): These bits select the data transfer factor (activation source). There
are some differences in activation sources for channel A and for channel B.
