Description
Specify the repeat size or block size.
When H'0001 is set, the repeat or block size is one byte,
one word, or one longword. When H'0000 is set, it
means the maximum value (refer to table 7.1). While the
DMA is in operation, the setting is fixed.
Indicate the remaining repeat or block size while the
DMA is in operation. The value is decremented by 1
every time data is transferred. When the remaining size
becomes 0, the value of the BKSZH bits is loaded. Set
the same value as the BKSZH bits.
