This value becomes the I 2 C slave address for the main memory when the ASEL (Table 02h, Register 89h) bit is
set. If A0h is programmed to this register, the auxiliary memory is disabled.

Allows for right-shifting the final answer of MON3 coarse voltage measurement. This allows for scaling the
measurement to the smallest full-scale voltage and then right-shifting the final result so the reading is weighted to
the correct LSB.
