21.3.6 Set Enable Error Interrupt Register (DMA_SEEI)
The SEEI provides a simple memory-mapped mechanism to set a given bit in the EEI to
enable the error interrupt for a given channel. The data value on a register write causes
the corresponding bit in the EEI to be set. Setting the SAEE bit provides a global set
function, forcing the entire EEI contents to be set. If the NOP bit is set, the command is
ignored. This allows you to write multiple-byte registers as a 32-bit word. Reads of this
register return all zeroes.
Address: DMA_SEEI is 4000_8000h base + 19h offset = 4000_8019h
