Functions
Data format is as follows:
*Write 5Vsb Alarm Threshold (command 0xBA)
Writes the 5Vsb Alarm Threshold.
Use the SMB write word to write this word data
Data format is as follows:
*Write Fan Speed Alarm Threshold (command 0xBC)
Writes the Fan Speed Alarm Threshold.
Bit
Description
7..0
-12V Under Voltage Alarm Threshold. Unsigned 8-bit
data, the LSB is 0.1%. If the -12V voltage is lower than
this threshold, the MCU triggers a voltage alarm. The
threshold range is between 0 and 250
15..8
-12V Over Voltage Alarm Threshold. Unsigned 8-bit data,
the LSB is 0.1%. If the -12V voltage is higher than this
threshold, the MCU triggers a voltage alarm. The
threshold range is between 0 and 250

Description
7..0
5Vsb Under Voltage Alarm Threshold. Unsigned 8-bit
data, the LSB is 0.1%. If the 5V standby voltage is
lower than this threshold, the MCU triggers a voltage
alarm. The threshold range is between 0 and 250
