PKV
0
When this bit is set to 1, it enables an interrupt when the period used to detect the
peak value in the voltage channel has ended.
25
CRC
0
When this bit is set to 1, it enables an interrupt when the latest checksum value is
different from the checksum value computed when Run register was set to 1.

Description
Reserved. These bits are always 0.
When this bit is set to 1, Phase A current generates Bit 17 (OI) in the STATUS1 register.
When this bit is set to 1, Phase B current generates Bit 17 (OI) in the STATUS1 register.
When this bit is set to 1, Phase C current generates Bit 17 (OI) in the STATUS1 register.
Reserved. These bits are always 0.
When this bit is set to 1, Phase A voltage generates Bit 18 (OV) in the STATUS1 register.
When this bit is set to 1, Phase B voltage generates Bit 18 (OV) in the STATUS1 register.
When this bit is set to 1, Phase C voltage generates Bit 18 (OV) in the STATUS1 register.
0: Phase A voltage is above SAGLVL level for SAGCYC half line cycles
1: Phase A voltage is below SAGLVL level for SAGCYC half line cycles
When this bit is switches from 0 to 1 or from 1 to 0, the Phase A voltage generates Bit 16
(SAG) in the STATUS1 register.

0: Phase B voltage is above SAGLVL level for SAGCYC half line cycles
1: Phase B voltage is below SAGLVL level for SAGCYC half line cycles
When this bit is switches from 0 to 1 or from 1 to 0, the Phase B voltage generates Bit 16
(SAG) in the STATUS1 register.

0
0: Phase C voltage is above SAGLVL level for SAGCYC half line cycles
1: Phase C voltage is below SAGLVL level for SAGCYC half line cycles
When this bit is switches from 0 to 1 or from 1 to 0, the Phase C voltage generates Bit 16
(SAG) in the STATUS1 register.
