eDMA Set Enable Request Register (EDMA_SERQR)
The EDMA_SERQR provides a simple memory-mapped mechanism to set a given bit in the
EDMA_ERQRL to enable the DMA request for a given channel. The data value on a register
write causes the corresponding bit in the EDMA_ERQRL to be set. Setting bit 1 (SERQn)
provides a global set function, forcing the entire contents of EDMA_ERQRL to be asserted.
Reads of this register return all zeroes.
