DESCRIPTION
IN1 Undervoltage Threshold
VTH = 1.0 + n x 20mV (if R08[7] = 0)
VTH = 0.5 + n x 10mV (if R08[7] = 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.
IN2 Undervoltage Threshold
VTH = 1.0 + n x 20mV (if R08[6] = 0)
VTH = 0.5 + n x 10mV (if R08[6] = 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.
IN3 Undervoltage Threshold
VTH = 1.0 + n x 20mV (if R08[5] = 0)
VTH = 0.5 + n x 10mV (if R08[5] = 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.
IN4 Undervoltage Threshold
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.
IN1 Overvoltage Threshold
VTH = 1.0 + n x 20mV (if R08[7] = 0)
VTH = 0.5 + n x 10mV (if R08[7] = 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.
