^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 633) In order to overcome the limitation of maximum number of registers
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 634) supported, the hardware separates register into different groups called
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 635) 'pages.' Each page is able to include up to 255 registers.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 636)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 637) The default page after power up is 0x82; therefore, if one has to get
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 638) access to register 0x8301, one has to use following sequence to switch
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 639) to page 0x83, then start reading/writing from/to offset 0x01 by using
