The same value should be set in ETCRH and ETCRL.
In repeat mode, operation continues until the DTE bit is cleared. To end the transfer operation, therefore, you should clear
the DTE bit to 0. A transfer end interrupt request is not sent to the CPU or DTC.
By setting the DTE bit to 1 again after it has been cleared, the operation can be restarted from the transfer after that
terminated when the DTE bit was cleared.
Figure 7-7 illustrates operation in repeat mode.
Transfer requests (activation sources) consist of A/D converter conversion end interrupts, external requests, SCI
transmission data empty and reception data full interrupts, and TPU channel 0 to 5 compare match/input capture A
interrupts. External requests can be set for channel B only.
