The power event register (Table 8) records changes in
the power status of the four ports. Any change in
PGOOD_ (R10h[7:4]) sets PG_CHG_ to 1. Any change
in the PWR_EN_ (R10h[3:0]) sets PWEN_CHG_ to 1.
PG_CHG_ and PWEN_CHG_ trigger on the edges of
PGOOD_ and PWR_EN_ and do not depend on the
DET_END_/CL_END_ is set high whenever detection/
classification is completed on the corresponding port. A
1 in any of the CL_END_ bits forces R00h[4] to 1. A 1 in
any of the DET_END_ bits forces R00h[3] to 1. As with
any of the other events register, the detect event register
