REGISTER 3-21:
Defines CF pulse width from 0 to 255. Length of width is value * 8 * (1/LINEFREQ) /
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.
REGISTER 3-22:
8-bit signed value. Represents the number of shifts for active power energy register
ENERGY_W_L before CFNUM is applied.
REGISTER 3-23:
Active power gain to produce a specified pulses per watt-hour. The value is always less
than one (for example, 32,767 = 0.9999695).
