DESCRIPTION

The actual time interval is calculated as: 

 

ADC_Frame_Time = ( AIFT + 1 ) * ( 25 nSec ). 

Where 0 <= AIFT <= 2147483648. 

 

Anything below 5 uSec will be limited by the intra-sample timing which is limited to 5 uSec at a minimum. 

Thus, the ADC frame time is adjustable from 5 microseconds to 53.68 seconds in 25 nanosecond steps. 

 

Range: 5 uSec to 53.68 Seconds. 

Resolution: 25 nanoseconds.
