Initial value is uncertain.
These registers are 16-bit write-only buffers that set accumulation gain of the digital filter. They
cannot be read. They can be accessed by word access only. Accumulation gain can be set to
gain 1 value as the maximum value. Byte access gives unassured results. If read is attempted,
an undetermined value is read out.
These registers are not initialized by a reset or in standby mode. Be sure to write data in them
before processing starts.
In the digital filter, output gain and accumulation gain can be adjusted separately. Take output
gain into account when setting accumulation gain.

These registers are 16-bit write-only buffers that determine the cutoff frequency f1 and f2. They
cannot be read. They can be accessed by word access only. Byte access gives unassured results.
If read is attempted, an undetermined value is read out.
These registers are not initialized by a reset or in standby mode. Be sure to write data in them
