Section 11 EXDMA Controller (EXDMAC)
11.3.5
EDBSR sets the repeat size, block size, or cluster size. EDBSR is enabled in repeat transfer, block
transfer, and cluster transfer modes. EDBSR is disabled in normal transfer mode.
When BKSZH and BKSZ are set to H'0001 in cluster transfer mode (dual address mode), the
EXDMAC operates in block transfer mode (dual address mode).

Description
Sets the repeat size, block size, or cluster size.
When these bits are set to H'0001, one byte-, one
word-, or one longword-size is set. When these bits are
set to H'0000, the maximum values are set (see table
11.2). These bits are always fixed during an EXDMA
operation.
In an EXDMA operation, the remaining repeat size,
block size, or cluster size is indicated. The value is
decremented by one each time of a data transfer. When
the remaining size becomes zero, the BKSZH value is
loaded. Set the same initial value as for the BKSZH bit
when writing.
