TCS3472 − Principles of Operation
To further control when an interrupt occurs, the device provides
a persistence filter. The persistence filter allows the user to
specify the number of consecutive out-of-range Clear
occurrences before an interrupt is generated. The persistence
filter register (0x0C) allows the user to set the Clear persistence
filter (APERS) value. See the persistence filter register for details
on the persistence filter value. Once the persistence filter
generates an interrupt, it will continue until a special function
interrupt clear command is received (see command register).
