Which SPn_ERR_STAT errors cause SPn_ERR_RATE's ERROR_RATE_CNT bits to increment

Hi

C6472, DIO lib 1.1.0 DirectIO

Which SPn_ERR_STAT bits cause SPn_ERR_RATE's ERROR_RATE_CNT bits to increment? 

And when the SPn_ERR_THRESH is reached, is that when bit 8 "Error on Port 0"  in ERR_RST_EVNT_ICSR is set?

What happens if its a fatal error (i.e. bit 2 of SPn_ERR_STAT). Is bit 8  "Error on Port 0" of ERR_RST_EVNT_ICSR set immediately?
