7.2.3
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.
7.2.4
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.
7.2.5
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 register 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 register 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
