entry key writing, the address will keep default value 98h.

For example, use 30k resistor for address 6A selection. User need to

write entry key to register CRFAh.

Ex: Original chip default address is 98h

Bus Access Byte Write (98, FA, 19)

Bus Access Byte Write (98, FA, 34)

Bus Access Byte Write (98, FA, 01)

After Entry Key writing, Chip address will change to 6Ah.

6.4 Temperature Monitoring

The F75393 monitors a local and a remote temperature sensor. Both can be measured from -40°C to 127.875°C.

6.5 Alert#

Five events can trigger ALERT# to low:

(1). VT1(Local) temperature exceeds High Limit

(2). VT1(Local) temperature goes below Low Limit

(3). VT2(Remote) temperature exceeds High Limit

(4). VT2(Remote) temperature goes below Low Limit

(5). VT2(Remote) temperature is Open-circuit.
