Part Number: TMS320F28377D
Hello, I contact you because I am working in a Test Team on the C2000 Target with corresponding technical reference TMS320F2837xD Dual-Core Microcontroller
While testing a system control intialization in case of robustness test, I configured CLKcfg registers this way :
=> selecting XTAL source in OSCCLKSRCSEL register
=> Setting XTALOFF to 1 (Put XTAL on OFF state)
Normally, according to the technical reference manual, when a missing clock is detected (which should be the case when you select a clk source and disable the corresponding clk source), MCLKSTS is raised (value 1) and the backup internal clock INTOSC1 if forced as the primary clock to avoid tsystem failure.
However, in my case, the code still run so I suppose there is a backup clock as specified but the MCLKSTS flag does not raised to alert on missing clock.
I would like to know if there is something that I don't get in the technical reference or if it is a problem from the Missing clock detection on the chip.
NB : The flag MCLKSTS raised correctly when I tried to do the same robustness case selecting INTOSC2 and setting INTOSC2 to OFF
