Program Action

At power-up in RUN mode, or when the
processor is switched from PROG to RUN,
the user program enables a block transfer
read. Then it initiates a block transfer write
to configure the module and send data
values.

Thereafter, the program continuously
performs read block transfers and write
block transfers.

Note: You must create the data file
for the block transfers before you
enter the block transfer instructions.
