UCC28C42: Adding UV and OV alarms or PGOOD to Flybacks

Hello Sir,

I am designing a Power supply for the following config.

UCC28C45

Vin (Min) (V): 85
Vin (Max) (V): 265
Vout (Nom) (V): 12
Iout (Max) (A): 5
Output Power (W): 60

UCC28C42

Vin (Min) (V): 36
Vin (Max) (V): 75
Vout (Nom) (V): 12
Iout (Max) (A): 5
Output Power (W): 60
Isolated/Non-Isolated: Isolated

I want to raise alarm for under and over voltage in my power supply design. How to do it?
