TMD2636 − Register Description

The binary search target field is used by the calibration feature

to set the baseline value for PDATA when no target is present.

For example, calibration of a device in open air, with no target,

and BINSEARCH_TARGET setting of 2 causes the PDATA value

will be approximately 15 counts. This feature is useful because

it forces PDATA result to always be above zero.

The PROX_AVG field sets the number of ADC samples that are

averaged. Each ADC sample causes the programmed number

of proximity pulses to be transmitted. Once all samples have

been completed and the average is calculated, the proximity

state machine will then pass this value either directly to PDATA

or to the proximity moving average filter depending on the

configuration of the PMAVG bits in the PFILTER register.
