10.3.4
The DMA channel control registers (CHCR) are 32-bit readable/writable registers that control the
DMA transfer mode.
The DO, AM, AL, DL, and DS bits which specify the DREQ and DACK external pin functions
can be read and written to in channels 0 to 3, but they are reserved in channels 4 to 7. The TL bit
which specifies the TEND external pin function can be read and written to in channels 0 and 1, but
it is reserved in channels 2 to 7.

Description
Transfer Count Mode
Specifies whether to transmit data once or for the
count specified in DMATCR by one transfer request.
This function is valid only in on-chip peripheral module
request mode. Note that when this bit is set to 0, the
TB bit must not be set to 1 (burst mode). When the
SCIF, IIC3, SSI, FLCTL, or SSU is selected for the
transfer request source, this bit (TC) must not be set
to 1.
0: Transmits data once by one transfer request
1: Transmits data for the count specified in DMATCR
Reserved
This bit is always read as 0. The write value should
always be 0.
