1 Introduction
Test Name: Clock Line Frequency Test
Purpose of test: Detect unexpected deviations in system clock frequency. Description: This diagnostic test checks the stability and reliability oscillation at the expected clock frequency. This test uses the Alternative Current (AC) line frequency to verify proper CPU clock operation. The AC line frequency is measured by using a Zero-Cross Detection (ZCD) circuit that is connected to the input of the Timer1 Gate module.API Documentation:
