eDMA Set Enable Error Interrupt Register (EDMA_SEEI)

The EDMA_SEEI provides a simple memory-mapped mechanism to set a given bit in the EDMA_EEI to
enable the error interrupt for a given channel. The data value on a register write causes the corresponding
bit in the EDMA_EEI to be set. Setting the SAEE bit provides a global set function, forcing the entire
EDMA_EEI contents to be set. Reads of this register return all zeroes.

eDMA Clear Enable Error Interrupt Register (EDMA_CEEI)
The EDMA_CEEI provides a simple memory-mapped mechanism to clear a given bit in the EDMA_EEI
to disable the error interrupt for a given channel. The data value on a register write causes the
corresponding bit in the EDMA_EEI to be cleared. Setting the CAEE bit provides a global clear function,
forcing the EDMA_EEI contents to be cleared, disabling all DMA request inputs. Reads of this register
return all zeroes.
