    Hi,

    Have you considered using the RTI as timer?

    The WCAP instruction of NHET is designed for capture timestamps. Please refer to WCAP instruction in device TRM.

    In HAL code, the last instruction used is WCAP to capture the value of register T which is used by CNT instruction. I don't know how to set the local time using N2HET instruction.

    hetGetTimestamp() will return zero in first LRP.
