MSTR Transaction #1
In this example, the MSTR blocks are executed sequentially. The Control Block and Data Block
registers for the first MSTR must be loaded with the following data before the MSTR block is
executed. This MSTR writes to the Acceleration Time 1 register (C1-01) and the Deceleration
Time 1 register (C1-02) to drive (at node 2).
