The voltage reading registers reflect the current voltage of the LM93 voltage monitoring inputs. Voltages are presented in the

registers at

⁄

full scale for the nominal voltage. Therefore, at nominal voltage, each register reads C0h.

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.
