Section 10
10.3.6
DMARS are 16-bit readable/writable registers that specify the DMA transfer sources from
peripheral modules in each channel. DMARS0 specifies for channels 0 and 1, DMARS1 specifies
for channels 2 and 3, and DMARS2 specifies for channels 4 and 5. This register can set the
transfer request of SCIF0, SIOF1, MMC, CMT (channels 0 to 4), SIM, USBF, SIOF0, SIOF1, and
SDHI.
When MID/RID other than the values listed in table 10.2 is set, the operation of this LSI is not
guaranteed. The transfer request from DMARS is valid only when the resource select bits (RS3 to
RS0) have been set to B'1000 for CHCR_0 to CHCR_5 registers. Otherwise, even if DMARS has
been set, transfer request source is not accepted.
