1) Select the PGA gains in the phase currents, voltages and
neutral current channels: Bits 2:0 (PGA1), Bits 5:3 (PGA2) and
Bits 8:6 (PGA3) in Gain register.
2) If Rogowski coils are used, enable the digital integrators in
the phase or neutral currents channels: Bit 0 (INTEN) in
CONFIG register and Bit 3 (ININTEN) in CONFIG3 register.
