TMS320F28388D: RESC is cleared on boot - how to know the reset source?

Part Number: TMS320F28388D

Hi,

As per the documentation, I could see the RESC for the reset source. However, for POR and Xrsn it says that it will be cleared by BOOT ROM.

Also, its mentioned in Table 5-68. CPU1 Boot Status Address, that the contents of the reset status would be copied in to address 0x0000 0002.

Below is the snapshot of the address and it reads zero's. I am specifically interested to know the POR vs Reset pin's Reset, as in my application a watchdog would be connected to the reset pin. Is there a way I can get this data once I start my application.
