Section 9 EXDMA Controller (EXDMAC)
If repeat area overflow occurs while a block is being transferred in block transfer mode, the repeat
interrupt request is held pending until the end of the block, and transfer overrun will occur. Figure
9.10 shows an example in which block transfer mode is used together with the repeat area
function.

When lower 3 bits (8-byte area) of EDSAR are designated as repeat area (SARA4 to SARA0 = 3),
and block size of 5 (EDTCR[23–16] = 5) is set in block transfer mode
