Hi ADI experts
I have a customer who is using ADM1278 for hot swap controller has a problem to read READ_PIN register(address:0x97) by BMC controller through PMBUS,
somtimes they can get a correct value for PIN but somtimes they don't and get just 0
Please see the below pictures for this problem.
I have discussed with the customer and they are very certain that they read the correct bits of READ_PIN register
also, they used continuously average reading mode for the PIN value (power monitor configuration register (address:0xD4) set to 0x071E)
any comment and suggestion would be appreciate.
1) "[REG %d]" is raw data.
2) "HSC Input Power = [%.3f] W" is converted input.
