 The encoder read operations follows the external trigger input as indicated in the timing diagram. ​ The largest jitter component comes from the delay in executing the interrupt service routine that performs the read operations. ​ Most of the time the interrupt proceeds with the minimum delay time specified. ​ Occasionally,​ the reads are delayed until current data bus operations complete.  ​ The encoder read operations follows the external trigger input as indicated in the timing diagram. ​ The largest jitter component comes from the delay in executing the interrupt service routine that performs the read operations. ​ Most of the time the interrupt proceeds with the minimum delay time specified. ​ Occasionally,​ the reads are delayed until current data bus operations complete.  ​
