the connection short the two input signals together on the output pins. The shorting resistance between the two input pins 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 pins of this device.

Writing zero to this bit sets page 0 as the active page for following register accesses. Writing a one to
this bit sets page 1 as the active page for following 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.
