VCC reading. The unit of reading is 8mV.
V1 reading. The unit of reading is 8mV.
V2 reading. The unit of reading is 8mV.
V3 reading. The unit of reading is 8mV.
Temperature 1 reading (MSB). The unit of reading is 1
reading this register, the LSB will be latched. This will prevent from data updating
when reading. To read the temperature value correctly, read MSB first and
followed read the LSB.
Temperature 2 reading (MSB). The unit of reading is 1
reading this register, the LSB will be latched. This will prevent from data updating
when reading. To read the temperature value correctly, read MSB first and
followed read the LSB.
FAN1 count reading (MSB). At the moment of reading this register, the LSB will
be latched. This will prevent from data updating when reading. To read the fan
count correctly, read MSB first and followed read the LSB.

Description
Serial Bus address. Power on default value depends on the status of pin3
(PWMOUT1/ADDR_TRAP) at the moment of power on. If the pin is pull-up
by 10K or none, the value is 5Ah; if the pin is pull-up by 2.2k or 200k, the
value is 5Ch.
To read or write registers of this chip, the serial address must match this
value.
This register can be written by a sequence value to this register: A9h, C3h,
XXh, in which XXh will be the value being written to this register; this is to
protect the register from being written by accident.
Write XXh to this register will return to default value.
