2. Registers 40031 and 40032 contain unscaled
frequency values. In order to obtain a full-scale
frequency value, use the following formula:
Scales Frequency + (20,000,000 / Period Count)
Notes:
1. Registers 40025 - 40030 contain unscaled voltage
values In order to obtain a full-scale voltage value,
use the following formula:
Voltage = (A/D Raw Value / 192) x
Full Scale Voltage (Register 40021)
