Limit

These registers allow a user limit to be set for the PROCHOT monitoring function. If the corresponding

Current Px_PROCHOT register exceeds this value, the PH1_ERR or PH2_ERR bit is set in the

corresponding Host and BMC error status registers. A value of FFh acts as a mask and prevents the error

status bits from being set.
