High-Rate Result (Output Registers)
These output registers contain the instantaneous values of voltage, current, power and quadrature power.
The high-rate registers are updated at the ADC Sampling Frequency (4.0 kHz). These register, given the
relatively high update rate, should be accessed with a high speed interface such as SPI.

Note:
1) The high rate registers are updated at the ADC converter sample rate. In order to access real
time data it is preferable to utilize the SPI interface.
