Address Selection

Links LK1 & LK3 are provided for appropriate address

selection as explained in the technical data sheet. LK1
corresponds to A0 while LK3 corresponds to A1. Position A

corresponds to 0 (GND) while position B corresponds to 1
(VDD). The default position of these links is A0A1 = 00
which gives a hexadecimal address of 0x48.
