During auto-reloading, the channel registers are reloaded with their initial values at the comple-
tion of each block and the new values used for the new block. Depending on the row number in

reloaded from their initial value at the start of a block transfer.
In this case, the address between successive blocks is selected to be a continuation from the
end of the previous block. Enabling the source or destination address to be contiguous between
