Disabling a Channel Prior to Transfer Completion
Under normal operation, software enables a channel by writing a ‘1’ to the Channel Handler
Enable Register, DMAC_CHER.ENABLE[n], and hardware disables a channel on transfer com-
pletion by clearing the DMAC_CHSR.ENABLE[n] register bit.
The recommended way for software to disable a channel without losing data is to use the SUS-
PEND[n] bit in conjunction with the EMPTY[n] bit in the Channel Handler Status Register.
