DMA Channel Control Registers 0, 1 (CHCR0, CHCR1)
DMA channel control registers 0, 1 (CHCR0, CHCR1) is a 32-bit read/write register where the
operation and transmission of each channel is designated. Bits 31 to 19 and bit 7 should always
read 0. The written value should also be 0. They are initialized to 0 by a power-on reset and in
software standby mode.
