16.0 Registers
16.6.3 Register 56–65h A/D Channel Voltage Registers
The voltage reading registers reflect the current voltage of the LM93 voltage monitoring inputs. Voltages are presented in the
registers at
16.6.4 Register 67h Current P1_PROCHOT
This is the value of the PROCHOT percentage active time for Processor 1 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 both PROCHOT channels (P1_PROCHOT and P2_PROCHOT). A register value of one represents anything
greater than 0% but less than 0.39% of active time.
