DMACHn Channel Interrupt Flag
Each bit in this field represents an interrupt for the corresponding channel interrupt
m. To clear an interrupt, clear the corresponding active interrupt bit in the
DMACHn_ST register. An interrupt bit in this field is set only if the corresponding
interrupt enable field is set in the DMAm_CN register. Register bits associated with
unimplemented channels should be ignored.
0: No interrupt
1: Interrupt pending
