P1_PROCHOT

76543210N/D

This is the average percentage active time of P1_PROCHOT. It is the result of adding the contents of this register to the contents

of the Current P1_PROCHOT register and dividing the result by 2. The update occurs at the same time that the Current

P1_PROCHOT register gets updated. A register value of one represents anything greater than 0% but less than 0.39% of active

time.

00h

This is the value of the PROCHOT percentage active time for Processor 2 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.
