to page 0x83, then start reading/writing from/to offset 0x01 by using
the register read/write sequence described in previous section.

Registers are represented in 16 bits values. The higher 8 bits represent
the page address and the lower 8 bits represent the relative offset within
that particular page. Refer to the 'Programming Sequence for Page Register
