DTCADMOD is used to select an address mode that specifies DTC's accessible area.
SHORT Bit (Short-Address Mode)
Full-address mode allows the DTC to access to a 4-Gbyte space (00000000h to FFFFFFFFh).
Short-address mode allows the DTC to access to a 16-Mbyte space (00000000h to 007FFFFFh and FF800000h to
FFFFFFFFh).

DTCST is used to start or stop the DTC module.
DTCST Bit (DTC Module Start)
Set the DTCST bit to 1 to enable the DTC to accept start requests. When this bit is cleared to 0, start requests are no
longer accepted.
If this bit is cleared to 0 during data transfer, the accepted start request is active until the processing is completed.
To enable transitions to the module-stop state, all-module clock-stop state, software-standby mode, or deep
software-standby mode, the DTCST bit must be set to "0".
For details on the facilities for transitions to the module-stop state, all-module clock-stop state, software-standby mode,
and deep software-standby mode, refer to section 13.8.1, Setting the DTC Module Start Register, and section 8, Low
Power Consumption.
