These registers are 16-bit write-only buffers that set accumulation gain of the digital filter. Only a
word access is valid. Accumulation gain can be set to gain 1 value as maximum value. If a byte
access is attempted, correct operation is not guaranteed. If a 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. Only a
word access is valid. If a byte access is attempted, correct operation is not guaranteed. If a 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.
