[Cortex-A53] Exception Syndrome Register - Exception Class

Hi,

I'm searching for the documentation for the exception classes in ESR_ELx. But currently couldn't found any information.

Want to port my bare-metal applications to AArch64. I own a PINE64 Rock64 (quad core Cortex-A53) board, which I want

to use as development platform to test the ported applications. 

Is there a list of the exception classes?

Searched in the TRM of the Cortex-A53. But didn't find any information.

I'm a newbie on this platform.

Thanks in advance!
