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.

Left Channel Audio Effects Filter N0 Coefficient MSB
The 16-bit integer contained in the MSB and LSB registers for this coefficient are interpreted as a 2’s
complement integer, with possible values ranging from –32768 to +32767.
(1)
When programming any coefficient value in Page 1, the MSB register should always be written first, immediately followed by the LSB
register. Even if only the MSB or LSB of the coefficient changes, both registers should be written in this sequence.
