High-Power, Quad, Monolithic, PSE Controllers
for Power over Ethernet
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

two addresses. When read through the R02h address,
the content of the register is left unchanged. When read
through the CoR R03h address, the register content is
cleared. A reset sets R02h/R03h = 00h.
