TCS3771 − Principles of Operation

proximity interrupt low threshold (PILTx) or exceeds the

proximity interrupt high threshold (PIHTx). It is important to

note that the low threshold value must be less than the high

threshold value for proper 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 RGBC or

proximity occurrences before an interrupt is generated. The

persistence register (0x0C) allows the user to set the RGBC

persistence (APERS) and the proximity persistence (PPERS)

values. See the persistence register for details on the

persistence filter values. Once the persistence filter generates

an interrupt, it will continue until a special function interrupt

clear command is received (see “Command Register” on

page 26).
