Description
Reserved
These bits are always read as 0 and cannot be
modified.
Block Size
These bits specify the block size (number of bytes
or number of words) for block transfer. Setting
H'01 specifies one as the block, while setting H'00
specifies the maximum block size, that is 256. The
register value always indicates the specified block
size.
16-Bit Transfer Counter
These bits specify the number of block transfers.
Setting H'0001 specifies one block transfer.
Setting H'0000 means no specification for the
number of transfers, and the transfer counter
function is halted. In this case, there is no transfer
end interrupt by the transfer counter. Setting
H'FFFF specifies the maximum number of block
transfers, that is 65,535. During EXDMA transfer,
this counter shows the remaining number of block
transfers.
