Question on TLF35584 Fail Safe State

Hello,

I have below question about TLF35584 device functionality. Can you please clarify ?

Item#1: I am trying to create below failure scenario.
1. Apply VBATT/12V to TLF35584
2. Observed that Rest pin of MCU is released by TLF35584 and all power supplies are up and running
3. Creating a MCU stuck fault scenario (This means no SPI communication or watchdog refresh from MCU)
4. Observed that after 600ms TLF35584 pulls reset pin low for 20ms and then releases Reset pin of MCU
5. Again Creating a MCU stuck fault scenario (This means no SPI communication or watchdog refresh from MCU)
6. Observed that after 600ms TLF35585 pulls reset pin low and remains low
After Step#6, If I apply Enable/Key-On the TLF35584 device is not recoverable

Is this behavior correct ?
Question#1.1: In Step#6, based on datasheet I thought TLF35584 will try to reset MCU at-least 3 times, however there is no retry from TLF35584 device ? Am I missing something ?
Question#1.2 In this case why Enable/Key-On is not able to recover TLF35584 device ?
