Determining regis-
ter numbers
In this chapter, only the last two figures of a register number are specified. e.g.
MR 14. To calculate the complete register number, add the basic register number
of the corresponding device, e.g. 103100, to the module register number.
INFO
When entering values into registers MR 1 through MR 6, the entire interface is
re-initialized and the transmit and receive buffers are cleared.
