==== Config options ====
Configuration has one switch group (A0, A1, A2) and one switch WP with two state  0 (short cut between middle pin and pin signed 0) and 1 (short cut between middle pin and pin signed 1).\\
  * A0 - address bit 0 (default set to 0)
  * A1 - address bit 1 (default set to 0)
  * A2 - address bit 2 (default set to 0)
  * WP - write protect where 1 mean protected, and 0 mean unprotected (default set to 0)
