Register 26: DMA Channel Map Select 3 (DMACHMAP3), offset 0x51C
Each 4-bit field of the DMACHMAP3 register configures the μDMA channel assignment as specified
in Table 9-1 on page 551.
Note: To support legacy software which uses the DMA Channel Assignment (DMACHASGN)
register, a value of 0x0 is equivalent to a DMACHASGN bit being clear, and a value of 0x1
is equivalent to a DMACHASGN bit being set.
