Returns 0 if no error was detected during autoload and Stuck At Zero Test passed 1 if no error was detected during autoload but Stuck At Zero Test failed 2 if there was a single-bit error detected during autoload 3 if some other error occurred during autoload

This function self checks the EFUSE module.

tms570_efc_check_self_test()

bool tms570_efc_check_self_test

(

void

)

EFUSE module self check Driver (HCG:checkefcSelfTest)

bool tms570_efc_stuck_zero

(

void

)

Checks to see if the EFUSE Stuck at zero test is completed successfully (HCG:efcStuckZeroTest). /.

Returns

1 if EFUSE Stuck at zero test completed, otherwise 0.

Checks to see if the EFUSE Stuck at zero test is completed successfully.

tms570_enable_parity()

void tms570_enable_parity

(

void

)

Enable peripheral RAM parity (HCG:enableParity)

This function enables RAM parity for all peripherals for which RAM parity check is enabled. This function is called before memoryInit in the startup
