CF_PULSE_WIDTH
Defines the CF pulse width from 0 to 255. Length of width is valued
* 8 * (1/LINE_FREQUENCY)/128) ms. A maximum of 0.266 seconds for 60 Hz and
0.319 seconds for 50 Hz.
* 8 * (1/LINE_FREQUENCY)/128) ms. A maximum of 0.266 seconds for 60 Hz and
0.319 seconds for 50 Hz.
If the value is 0, no CF pulse is produced.

GAIN_DENR_ENERGY_ACT
8-bit signed value. Represents the number of shifts for active power energy register
ENERGY_ACT before GAIN_DENR_ENERGY_ACT is applied.
ENERGY_ACT before GAIN_DENR_ENERGY_ACT is applied.
3.40
GAIN_NUMR_ENERGY_ACT
Active power gain to produce a specified pulses per watt-hour. The value is always less
than one (for example, 32,767 = 0.9999695).
than one (for example, 32,767 = 0.9999695).
