Figure 101. Example of JSQR queue of context with empty queue (case JQM=1)

(returned by reading JQSR)

1. Parameters:

P1: sequence of 1 conversion, hardware trigger 1

P2: sequence of 1 conversion, hardware trigger 1

P3: sequence of 1 conversion, hardware trigger 1

Flushing the queue of context

The figures below show the behavior of the context Queue in various situations when the

queue is flushed.

ADC J context

(returned by reading JSQR)

1. Parameters:

P1: sequence of 1 conversion, hardware trigger 1

P2: sequence of 1 conversion, hardware trigger 1

P3: sequence of 1 conversion, hardware trigger 1

Case when JADSTP occurs during an ongoing conversion.

Queue becomes empty

and triggers are ignored

because JQM=1

EMPTY (0x0000)

Queue is flushed and maintains

the last active context

(P2 is lost)
