bit 6

Samp: Sample Mode Enable bit

This bit controls the enabling of Sample mode when the PS700 is not in a Power-on Reset,

Sample-Sleep or Shelf-Sleep mode. When set to ‘1’, Sample mode is enabled and conversions

will be performed at a periodic rate determined by the programming of the SampDiv bits. When

cleared, Sample mode is disabled and the PS700 will operate in Run mode.

= Sample mode enabled

= Sample mode disabled

bit 5-3

Reserved: Reserved bit location

bit 2-0

SampDiv: Sample Period Interval bits

The SampDiv bits determine the interval between sample periods when the PS700 is operating

in Sample mode. The programmed interval will be 2**(SampDiv) * 0.5 sec.
