RX62N Group, RX621 Group 4. Library Reference
Remarks
•
If address increment or decrement is selected, the address changes according to the number of
bytes (1, 2 or 4) in each transfer.
•
Before calling this function, call R_DTC_Set.
•
Call this function before configuring the peripherals that will be involved in the data transfer.
•
Call this function once for each peripheral that will trigger a transfer, and for each chained
transfer.
•
For chain transfers, each transfer data area in the chain must be contiguous.
•
When all calls to this function are complete, call R_DTC_Control to start the DTC.

/* Reserve 16 bytes (full address mode) for the CMT0-triggered transfer data
area */
/* Use a 32-bit type to make the address a multiple of 4 */
