Decimation Filter Register Descriptions
All registers are 32-bit wide, and each of the eight Decimation Filters on the device have the same register
interface.
28.2.2.1
Decimation Filter Module Configuration Register (DECFILT_x_MCR)
The Decimation Filter module configuration register provides configuration control bits for the
Decimation Filter internal logic.
NOTE
Do not modify this register’s contents when the status bit BSY is set, except
for fields FREN, FRZ and IDIS. To guarantee that BSY does not set during
the read-modify-write operation, it is advisable to set IDIS=1 and wait for
BSY=0 beforehand.
