8.2.3
SAR is a 24-bit register that designates the source address of data to be transferred by the DTC. For word-size transfer,
specify an even source address.
8.2.4
DAR is a 24-bit register that designates the destination address of data to be transferred by the DTC. For word-size
transfer, specify an even destination address.
8.2.5
CRA is a 16-bit register that designates the number of times data is to be transferred by the DTC.
In normal mode, the entire CRA functions as a 16-bit transfer counter (1 to 65,536). It is decremented by 1 every time
data is transferred, and transfer ends when the count reaches H'0000.
In repeat mode or block transfer mode, the CRA is divided into two parts: the upper 8 bits (CRAH) and the lower 8 bits
(CRAL). CRAH holds the number of transfers while CRAL functions as an 8-bit transfer counter (1 to 256). CRAL is
decremented by 1 every time data is transferred, and the contents of CRAH are sent when the count reaches H'00. This
operation is repeated.
