User Manual

An Interrupt can be generated with each new proximity

result or whenever proximity results exceed or fall below

levels set in the PIHT and/or PILT threshold registers. To

prevent premature/ false interrupts an interrupt persis-

tence lter is also included; interrupts will only be assert-

ed if the consecutive number of out-of-threshold results

is equal or greater than the value set by PPERS. Each “in-

threshold” proximity result, PDATA, will reset the persis-

tence count. If the analog circuitry becomes saturated,

the PGSAT bit will be asserted to indicate PDATA results

may not be accurate. The PINT and PGSAT bits are always

available for I²C polling, but PIEN bit must be set for PINT

to assert a hardware interrupt on the INT pin. Similarly,

saturation of the analog data converter can be detected

by polling PGSAT bit; to enable this feature the PSIEN bit

must be set. PVALID is cleared by reading PDATA. PGSAT,

and PINT are cleared by “address accessing” (i.e. I²C trans-

action consisting of only two bytes: chip address, followed

by a register address with R/W=1) PICLEAR or AICLEAR.
