0 is written to the bit among bits DTCENi0 to DTCENi1, DTCENi3 to DTCENi7 when transfer is either of the
following:
- Transfer causing the DTCCTj (j = 0 to 23) register value to change from 1 to 0 in normal mode
- Transfer causing the DTCCTj register value to change from 1 to 0 while the RPTINT bit is 1 in repeat mode
DTCENi0 to DTCENi1, DTCENi3 to DTCENi7: Bits in DTCENi (i = 0 to 3, 5, 6) registers
RPTINT, CHNE: Bits in DTCCRj registers
NMIF: Bit in DTCTL register
