Writing '0' to this bit sets Page-0 as the active page for following register accesses. Writing a '1' 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.
