9.2.2.7 eDMA Set Enable Error Interrupt Register (EDMA_SEEIR)
The EDMA_SEEIR provides a simple memory-mapped mechanism to set a given bit in the
EDMA_EEIRH or EDMA_EEIRL to enable the error interrupt for a given channel. The data value on a
register write causes the corresponding bit in the EDMA_EEIRH or EDMA_EEIRL to be set. Setting bit
1 (SEEI
n ) provides a global set function, forcing the entire contents of EDMA_EEIRH or EDMA_EEIRL
to be asserted. Reads of this register return all zeroes.
9.2.2.8 eDMA Clear Enable Error Interrupt Register (EDMA_CEEIR)
The EDMA_CEEIR provides a simple memory-mapped mechanism to clear a given bit in the
EDMA_EEIRH or EDMA_EEIRL to disable the error interrupt for a given channel. The data value on
a register write causes the corresponding bit in the EDMA_EEIRH or EDMA_EEIRL to be cleared.
Setting bit 1 (CEEI
n ) provides a global clear function, forcing the entire contents of the EDMA_EEIRH
or EDMA_EEIRL to be zeroed, disabling error interrupts for all channels. Reads of this register return
all zeroes.
