AFE4950: Interrupt output pulse problem

Hi TI Teams,

Our customer reported that they have encountered a problem about the interrupt pulse width when using the AFE4500. That is, when the ECG is turned on, the pulse width of the interrupt output is fixed to the width of 1 TE, which is 7.8125us (in the single PPG acquisition mode, the desired width can be output according to the software configuration). 

They configured 6 TE cycles through the software, and the output interrupt pulse width at this time should be 6 * 7.8125us. But when the ECG is turned on, the configuration is found to be invalid, the output interrupt pulse width is 7.8125us. 

Thanks,

Kind Regards
