IN4 Overvoltage Threshold Value (VTH):
VTH = 1.0 + n x 20mV (if R08[4] = 0)
VTH = 0.5 + n x 10mV (if R08[4] = 1)
where n is the register content decimal representation. Note that VTH
ranges must be 1V to 5.5V and 0.5V to 3.05V, respectively.
Bit 7—If 0, 20mV steps in VTH setting for IN1
If 1, 10mV steps in VTH setting for IN1
Bit 6—If 0, 20mV steps in VTH setting for IN2
If 1, 10mV steps in VTH setting for IN2
Bit 5—If 0, 20mV steps in VTH setting for IN3
If 1, 10mV steps in VTH setting for IN3
Bit 4—If 0, 20mV steps in VTH setting for IN4
If 1, 10mV steps in VTH setting for IN4
Bit 3—UV1 or OV1 Fault (read only for register address). If 1, IN1 is under
undervoltage threshold or over overvoltage threshold. If 0, IN1 is over
undervoltage threshold and under overvoltage threshold.
Bit 2—UV2 or OV2 Fault (read only for register address). If 1, IN2 is under
undervoltage threshold or over overvoltage threshold. If 0, IN2 is over
undervoltage threshold and under overvoltage threshold.
Bit 1—UV3 or OV3 Fault (read only for register address). If 1, IN3 is under
undervoltage threshold or over overvoltage threshold. If 0, IN3 is over
undervoltage threshold and under overvoltage threshold.

R/W
Bit 0—UV4 or OV4 Fault (read only for register address). If 1, IN4 is under
undervoltage threshold or over overvoltage threshold. If 0, IN4 is over
undervoltage threshold and under overvoltage threshold.
Bit [7:6] If “00” the device configuration is a single device
If “01” the device configuration is multiple devices, slave
If “10” the device configuration is multiple devices, slave
If “11” the device configuration is multiple devices, master
Bit 5—If 1, latch-on fault
If 0, autoretry
Bit [4:2] “000” autoretry timer value = 25s
“001” autoretry timer value = 12.5ms
“010” autoretry timer value = 25.0ms
“011” autoretry timer value = 50.0ms
“100” autoretry timer value = 100.0ms
“101” autoretry timer value = 200.0ms
“110” autoretry timer value = 400.0ms
“111” autoretry timer value = 1600.0ms
Bit 1—If 1, check I2C enable bit
If 0, ignore I2C enable bit
09h
29h
R/W
Bit 0—If 1 and 09h[1] = 1, I2C enabled
If 0 and 09h[1] = 1, I2C disabled
