Part Number: TMS320F28379D
Tool/software: Code Composer Studio
During free run/step over execution, the PC toggles between 0x008037 and 0x008038. The PC jumps to these two locations randomly and not at a definite line of code.
Stack is popped out using the instruction "SUBB ACC, #1" at address location "0x008037" after a function execution.
Branch Fast instruction "BF -1, GEQ" is executed at address location "0x008038" during the beginning of a function.
The above mentioned address locations are the end (SPI_enableFIFO()) and start (SPI_resetTxFIFO()) of SPI COTS functions.
Note: Although the watchdog is enabled during initialization, it gets disabled when the above phenomenon occurs.
Thank you in advance for all the responses.
