Use the above procedure to enter the required words of the write

block transfer instruction. Be aware that the block length will depend

on the number of channels selected and whether scaling is or is not

performed; for example, the block may contain only 3 words if no

scaling is performed but may contain 37 words if using 16 inputs

with scaling.
