Bit
Location Bit Mnemonic Default Value Description
10 CF2DIS 1
When this bit is set to 1, the CF2 output is disabled. The respective digital to frequency
converter remains enabled even if CF2DIS = 1.
When this bit is set to 0, the CF2 output is enabled.
11 CF3DIS 1
When this bit is set to 1, the CF3 output is disabled. The respective digital to frequency
converter remains enabled even if CF3DIS = 1.
When this bit is set to 0, the CF3 output is enabled.
12 CF1LATCH 0
When this bit is set to 1, the content of the corresponding energy registers is latched when a
CF1 pulse is generated. See the Synchronizing Energy Registers with CFx Outputs section.
13 CF2LATCH 0
When this bit is set to 1, the content of the corresponding energy registers is latched when a
CF2 pulse is generated. See the Synchronizing Energy Registers with CFx Outputs section.
14 CF3LATCH 0
When this bit is set to 1, the content of the corresponding energy registers is latched when a
CF3 pulse is generated. See the Synchronizing Energy Registers with CFx Outputs section.
15 Reserved 0 Reserved. This bit does not manage any functionality.

Bit
Location Bit Mnemonic Default Value Description
9:0 PHCALVAL 0000000000 If the current leads the voltage, these bits can vary only between 0 and 383.
If the current lags the voltage, these bits can vary only between 512 and 575.
If the PHCALVAL bits are set with numbers between 384 and 511, the compensation behaves
like PHCALVAL set between 256 and 383.
If the PHCALVAL bits are set with numbers between 576 and 1023, the compensation
behaves like PHCALVAL bits set between 384 and 511.
15:10 Reserved 000000 Reserved. These bits do not manage any functionality.

Bit
Location Bit Mnemonic Default Value Description
0 AWSIGN 0
0: if the active power identified by Bit 6 (REVAPSEL) in the ACCMODE register (total of
fundamental) on Phase A is positive.
1: if the active power identified by Bit 6 (REVAPSEL) in the ACCMODE register (total of
fundamental) on Phase A is negative.
1 BWSIGN 0
0:
if the active power identified by Bit 6 (REVAPSEL) in the ACCMODE register (total of
fundamental) on Phase B is positive.
1: if the active power identified by Bit 6 (REVAPSEL) in the ACCMODE register (total of
fundamental) on Phase B is negative.
2 CWSIGN 0
0: if the active power identified by Bit 6 (REVAPSEL) in the ACCMODE register (total of
fundamental) on Phase C is positive.
1: if the active power identified by Bit 6 (REVAPSEL) bit in the ACCMODE register (total of
fundamental) on Phase C is negative.
3 SUM1SIGN 0 0: if the sum of all phase powers in the CF1 datapath is positive.
1: if the sum of all phase powers in the CF1 datapath is negative. Phase powers in the CF1
datapath are identified by Bits[2:0] (TERMSEL1[x]) of the COMPMODE register and by
Bits[2:0] (CF1SEL[x]) of the CFMODE register.
4 AVARSIGN 0
0: if the reactive power identified by Bit 7 (REVRPSEL) in the ACCMODE register (total of
fundamental) on Phase A is positive. This bit is always 0 for ADE7854.
1: if the reactive power identified by Bit 7 (REVRPSEL) in the ACCMODE register (total of
fundamental) on Phase A is negative.
5 BVARSIGN 0
0: if the reactive power identified by Bit 7 (REVRPSEL) in the ACCMODE register (total of
fundamental) on Phase B is positive. This bit is always 0 for ADE7854.
1: if the reactive power identified by Bit 7 (REVRPSEL) in the ACCMODE register (total of
fundamental) on Phase B is negative.
6 CVARSIGN 0
0: if the reactive power identified by Bit 7 (REVRPSEL) in the ACCMODE register (total of
fundamental) on Phase C is positive. This bit is always 0 for ADE7854.
1: if the reactive power identified by Bit 7 (REVRPSEL) in the ACCMODE register (total of
fundamental) on Phase C is negative.
