Current/Voltage Threshold.
Determines the threshold at which an interrupt is generated from either the LCS or LVS regis-
ter. Generate this interrupt to occur when the line current or line voltage rises above or drops
below the value in the CVT[7:0] register.
Current/Voltage Interrupt.
0 = The current / voltage threshold has not been crossed.
1 = The current / voltage threshold is crossed. If the CVM and INTE bits are set, a hardware
interrupt occurs on the AOUT/INT pin. Once set, this bit must be written to 0 to be cleared.
Current/Voltage Select.
0 = The line current shown in the LCS2 register generates an interrupt.
1 = The line voltage shown in the LVS register generates an interrupt.
Current/Voltage Interrupt Mask.
0 = The current / voltage threshold being triggered does not cause a hardware interrupt on the
AOUT/INT pin.
1 = The current / voltage threshold being triggered causes a hardware interrupt on the AOUT/
INT pin.
Current/Voltage Interrupt Polarity.
0 = The current / voltage threshold is triggered by the absolute value of the number in either
the LCS2 or LVS register falling below the value in the CVT[7:0] register.
1 = The current / voltage threshold is triggered by the absolute value of the number in the
either the LCS2 or LVS register rising above the value in the CVT[7:0] Register.
