Section 7 DMA Controller (Not Supported in the H8S/2321)
Bit 5—Repeat Enable (RPE): Used in combination with the DTIE bit in DMABCR to select the
mode (sequential, idle, or repeat) in which transfer is to be performed.

For details of operation in sequential, idle, and repeat mode, see section 7.5.2, Sequential Mode,
section 7.5.3, Idle Mode, and section 7.5.4, Repeat Mode.
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.
