1.6.4 Setting PL260 protocol address
Two dip-switches are provided to configure the address of module for serial
communication with a master device. There are 4 available combinations of
these dip-switch. To connect more than 4 devices to the same network it is
necessary to change the address offset value.
The address is given as follows:
MODULE ADDRESS = ADDRESS OFFSET + DIP-SWITCH COMBINATION
The offset address, value stored on PL260 memory (default "1"), can be
modified by writing on SMW4 word.
Dip-switch combinations are:
Dip-switch combination = 0 Dip-switch combination = 1
Dip-switch combination = 2 Dip-switch combination = 3
