Function

Corrupted flash read when SVM low-side flag is triggered

Description

If the SVM low side is enabled, a change in the VCORE voltage level (an increase in the VCORE level) may cause the currently executed read operation from flash to be incorrect and may lead to unexpected code execution or incorrect data. This can happen under any one of the following conditions:

- When the VCORE is changed in application, the SVM low side is used to indicate if the core voltage has settled by using the SVMDLYIFG flag. The failure occurs only when a flash access is concurrent to the expiration of the settling time delay.

- Unexpected changes in the VCORE voltage level

For code examples and detailed guidance on the PMM operation and software APIs for PMM configuration see the driverlib APIs from 430Ware (MSP430Ware).

Workaround

- Execute the procedure to change the VCORE level from RAM.

or

- If executing from flash, follow the procedure below when increasing the VCORE level. Note: To apply this workaround, the SVM low-side comparator must operate in normal mode (SVMLFP = 0 in SVMLCTL).

// Set SVM highside to new level and check if a VCore increase is possible
  SVSMHCTL = SVMHE | SVSHE | (SVSMHRRL0 * level);
  // Wait until SVM highside is settled
  while ((PMMIFG & SVSMHDLYIFG) == 0);
  // Clear flag
  PMMIFG &= ~SVSMHDLYIFG;

  // Set also SVS highside to new level
  // Vcc is high enough for a Vcore increase
  SVSMHCTL |= (SVSHRVL0 * level);
  // Wait until SVM highside is settled
  while ((PMMIFG & SVSMHDLYIFG) == 0);
  // Clear flag
  PMMIFG &= ~SVSMHDLYIFG;
  
//**************flow change for errata workaround ************
  // Set VCore to new level
  PMMCTL0_L = PMMCOREV0 * level;


  // Set SVM, SVS low side to new level
  SVSMLCTL = SVMLE | (SVSMLRRL0 * level)| SVSLE | (SVSLRVL0 * level);
  // Wait until SVM, SVS low side is settled
  while ((PMMIFG & SVSMLDLYIFG) == 0);
  // Clear flag
  PMMIFG &= ~SVSMLDLYIFG;
