16.11.3 Register 56–65h A/D Channel Voltage Registers
The voltage reading registers reflect the current voltage of the LM96194 voltage monitoring inputs. Voltages are presented in the
registers at ¾ full scale for the nominal voltage. Therefore, at nominal voltage, each register reads C0h.
16.11.4 Register 67h Current PROCHOT
This is the value of the PROCHOT percentage active time for Processor at the end of each PROCHOT monitoring interval as set
by the PROCHOT Time Interval register. Writing to this register does not effect the register contents, but does restart the capture
cycle for PROCHOT. A register value of one represents anything greater than 0% but less than 0.39% of active time.
