CVT[7:0]

Current/Voltage Threshold.

These bits determine the threshold at which an interrupt is generated from either the LCS or

LVS register. This interrupt can be generated to occur when the line current or line voltage

rises above or drops below the value in the CVT[7:0] register.

Reserved Read returns zero.

3CVI

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.

2CVS

Current/Voltage Select.

0 = The line current shown in the LCS2 register is used to generate an interrupt.

1 = The line voltage shown in the LVS register is used to generate an interrupt.

1CVM

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.

0CVP

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 either

the LCS2 or LVS register rising above the value in the CVT[7:0] register.
