When the DTC is activated, control data (DTCCRj, DTBLSj, DTCCTj, DTRLDj, DTSARj, and DTDARj, j = 0 to
23) allocated in the control data area is read, and then transferred to the control registers (DTCCR, DTBLS,
DTCCT, DTRLD, DTSAR, and DTDAR) in the DTC. On completion of the DTC data transfer, the contents of the
DTC control registers are written back to the control data area.
Each DTCCR, DTBLS, DTCCT, DTRLD, DTSAR, and DTDAR register cannot be directly read or written to.
DTCCRj, DTBLSj, DTCCTj, DTRLDj, DTSARj, and DTDARj are allocated as control data at addresses from
2C40h to 2CFFh in the DTC control data area, and can be directly accessed.
Also, registers DTCTL and DTCENi (i = 0 to 3, 5, 6) can be directly accessed.
