Based on the settings of this register, if BOTH LINE1 and LINE2 inputs are routed to the output at the same time, then the two switches
used for the connection short the two input signals together on the output terminals. The shorting resistance between the two input
terminals is two times the bypass switch resistance (Rdson). In general, this condition of shorting should be avoided, as higher drive
currents are likely to occur on the circuitry that feeds these two input terminals of this device.

Page Select Bit
Writing zero to this bit sets page 0 as the active page for subsequent register accesses. Writing a one to
this bit sets page 1 as the active page for subsequent register accesses. It is recommended that the user
read this register bit back after each write, to ensure that the proper page is being accessed for future
register read/writes. This register has the same functionality on page 0 and page 1.
