Function
•
Distributes s into four bit sections and sets to the lower four bits of the n words starting from d.
•
The upper 12 bits of the range d to d + n – 1 will be “0.”
•
The value of s will be retained even if DIST is executed.
•
Use this instruction so that d + n - 1 does not exceed the I/O range (WRFFF and WM3FF). If it exceeds the I/O range, DER
is equal to '1' and the distribution data for s will be set in the lower four bits within the range between d and the I/O.
