Sampling methods are defined by three bits, as follows:

Sampling method

Binary value

Description

 

 

 

Reserved

000

Not defined.

 

 

 

Minimum

001

If more than one sample per slot is performed, the lowes value will be stored.

 

 

 

Maximum

010

If more than one sample per slot is performed, the highest value will be stored.

 

 

 

Sum

011

The sum of all samples for a certain slot will be stored.

 

 

 

Average (arithmetic)

100

If more than one sample per slot is performed, the arithmetic average of all samples

will be stored.

 

 

 

 

 

Average (circular)

101

If more than one sample per slot is performed, the average computed on a circle will

be stored (i.e. on a 0 to 359 deg. circle, overflow occurs at the 359 deg value).

 

 

 

 

 

First sample

110

If more than one sample per slot is performed, the first value will be stored. All other

samples are discarded.

 

 

 

 

 

Last sample

111

If more than one sample per slot is performed, the last value will be stored. All other

samples are discarded.
