3.9.15.4 MATH_PROC Parameter Dynamic Change
Some of the MATH_PROC parameters cannot be dynamically changed (when the data is being input/output
to/from the MATH_PROC corresponding to the parameter change). Update is possible only when the operation of
the corresponding MATH_PROC is suspended (the states other than from when "the data is input to the
MATH_PROC to the completion of preparing the data for output").
The following shows the registers that cannot be dynamically changed.

Description
Register Clear of DEC0 integrator
Register Clear of DEC1 integrator
Decimation ratio
When set to "1", regardless of the N1 value,
bypass is enforced with no sample delay

Effect of Changing Dynamically
The integrator cannot be reset because the initial state
of the integrator's counter is enforced
Same as above
The decimation ratio cannot be dynamically changed
since the data output is sometimes delayed. Also,
decimation cannot be turned ON from bypass mode.
Same as above
