Memory map/register definition
21.3.16 Channel n Priority Register (DMA_DCHPRIn)
When fixed-priority channel arbitration is enabled (CR[ERCA] = 0), the contents of these
registers define the unique priorities associated with each channel. The channel priorities
are evaluated by numeric value; for example, 0 is the lowest priority, 1 is the next
priority, then 2, 3, etc. Software must program the channel priorities with unique values.
Otherwise, a configuration error is reported. The range of the priority value is limited to
the values of 0 through 15.
Addresses: 4000_8000h base + 100h offset + (1d × n), where n = 0d to 15d
