Section 14 Direct Memory Access Controller (DMAC)
Bit 6—DREQ Select (DS): DS selects the sampling method of the DREQ pin that is used in
external request mode is detection in low level or at the falling edge.
This bit is only valid in CHCR0. This bit in CHCR1, CHCR2 and CHCR3 is always read as 0 and
should only be written with 0.
Also, it should be cleared to 0 (low-level detection) if an on-chip supporting module is specified as
a transfer request source in channel 0.

Bits 4 and 3—Transmit Size 1, 0 (TS1 and TS0): TS1 and TS0 specify the size of data to be
transferred.

Bit 2—Interrupt Enable (IE): Setting this bit to 1 generates an interrupt request when the
number of times of data transfers specified with DMATCR has completed (TE = 1).
