Section 7 Data Transfer Controller (DTC)
The DTC transfer mode can be normal mode, repeat mode, or block transfer mode.
The 24-bit SAR designates the DTC transfer source address and the 24-bit DAR designates the
transfer destination address. After each transfer, SAR and DAR are independently incremented,
decremented, or left fixed.
Table 7.2 outlines the functions of the DTC.
