10.3.2 IEC 60730 Self Test Library (available only in MCF8316DULVRGFR)

MCF8316DULVRGFR has an integrated Self Test Library (STL) to check the health of critical peripherals used in current and voltage sensing, digital logic and memory during power-up as well as motor operation - an unintended condition/operation detected during these self-tests result in a latched fault with specific fault information provided in CONTROLLER_FAULT_STATUS register.

The self tests performed during power-up can also be initiated by the user. The procedure to initiate self test is as follows,

  1. Self test should be initiated only when the device is in idle mode (motor is not driven by the device); hence, stop the motor by issuing a zero reference command. Read ALGORITHM_STATE (from 0x18E) variable to ensure the device is in idle state (read back value should be 0x0) or in fault state (read back value should be 0xE).
  2. Write 0x0000037C to ALGO_CTRL1 (at 0xEA) register to initiate self test sequence; initiation of self test sequence results in device reset.
  3. Wait for 500ms for the self test sequence to be completed.
  4. Read the CONTROLLER_FAULT_STATUS (at 0xE2) register to ensure there was no fault during self test sequence.
  5. In case of fault during self test sequence, issue another self test command to check if device recovers. In case of persistent faults, perform a power recycle to check if device recovers; if fault persists or device is unresponsive, the device (critical peripherals, digital logic or memory) may not work as expected.
