If the EDA bit in EDMDR is set to 1 during interrupt generation, transfer is resumed. Figure 9.9
illustrates the operation of the repeat area function.
Caution is required when the repeat area overflow interrupt function is used together with block
transfer mode. If transfer is always terminated when repeat area overflow occurs in block transfer
mode, the block size must be a power of two, or alternatively, the address register value must be
set so that the end of a block coincides with the end of the repeat area range.
