As stated in the Current Waveform Gain Registers section, the
serial ports of the ADE78xx work on 32-, 16-, or 8-bit words.
Similar to the register presented in Figure 34, the AIRMS,
BIRMS, CIRMS, and NIRMS (ADE7868/ADE7878 only) 24-bit
signed registers are accessed as 32-bit registers with the eight
MSBs padded with 0s.
