TPS65381 MCU Error Signal Monitor (No.166)

Hello,

Please advise how to understand following explanation of Datasheet (SLVSBC4B –MAY 2012–REVISED JULY 2014) P54.

 

  5.4.1.15 MCU Error Signal Monitor (MCU ESM)

     The module is covered by a logic BIST and is activated at a device power-up event or by the external MCU when the device is in the DIAGNOSTIC or ACTIVE state or SAFE state.

 

Q1:

Is it correct to understand above explanation as follows?

   The module is covered by a logic BIST and (logic BIST) is activated at a device power-up event or the external MCU when the device is in the DIAGNOSTIC or ACTIVE state or SAFE state.

 

Q2:

If above understanding is correct, LBIS_EN bit in SAFETY_BIST_CTRL can be updated only in DIAGNOSTIC and ACTIVE states. So datasheet is incorrect and  logic BIST can not be activated in SAFE state.

Please confirm above my understanding is correct or not.

 

Best Regards.
