Description
the value of PageSelect[2:0] is used as the register address
A5, A4, and A3. The LSBs of the register address are
defined using the address pins or the internal address latch,
respectively.
the complete content of the internal address latch defines
the register address. The address pins are used as
described in
Table 5 on page 8
