This read-only status bit shows the completion status of the filter selection.After setting the
FILTER_SEL in bits[4:0], this status bit will be set 1. After completion of the filter setting operation,
this bit will return to 0.
1: Filter setting is busy
0: Filter setting is completed
bit[4:0]
FILTER_SEL
Specifies the type of filter (moving average filter and FIR Kaiser filter) and TAP setting.
For the FIR Kaiser filter, these bits also selects the cutoff frequency fc in Hz.
After setting the filter with these bits, the completion of the operation requires time period
specified in Table 2.4 Filter Setting Time to elapse or confirming completion by checking
FILTER_STAT bit 5.
NOTE: Refer to 5.13 Filter for description of filter transient response from sampling start.
