Registers
When the DTC is activated, control data (DTCCRj, DTBLSj, DTCCTj, DTRLDj, DTSARj, and DTDARj, j = 0 to
23) allocated in the RAM 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.
The DTCCR, DTBLS, DTCCT, DTRLD, DTSAR, and DTDAR registers cannot be accessed directly.
DTCCRj, DTBLSj, DTCCTj, DTRLDj, DTSARj, and DTDARj can be directly accessed by the system bus.
Also, registers DTCTL and DTCENi (i = 0 to 3, 5, or 6) can be accessed via the peripheral bus.
