4 PIC18 Diagnostic Test APIs
4.2 SW_CLOCK_PERIODIC_MONITOR_01
This module contains APIs to calculate and validate the frequency of the CPU clock using a reference Secondary Oscillator Crystal. The Clock test implements the SW_CLOCK_PERIODIC_MONITOR_01 SW REQ. ID by using time-slot monitoring technique.. It verifies the reliability of the system. clock (i.e., the system clock should be neither too fast nor too slow)
4.2.3 Functions
4.2.3.3 diag_ClockTestTimer
For the SW_CLOCK_PERIODIC_MONITOR_01 API to calculate the diag_clockCount value to be used in GUID-CA6431D6-0107-4747-8D13-AAD13ED2CE7E.html API.
