19.2.10 DTC Transfer Count Reload Register j (DTRLDj) (j = 0 to 23)
This register is used to set the initial value of the transfer count register in repeat mode. Since the value of this register
is reloaded to the DTCCT register in repeat mode, set the same value as the initial value of the DTCCT register.
