In addition to these registers, the interrupt control provides four pairs of mask registers that can be used to
monitor message, interprocessor, timer, and external interrupts. See
Mask Registers (PMMRs),” on page

This section describes the performance monitor control registers in detail.
20.3.2.1

Freeze all counters.
0 PMCs are incremented (if permitted by other PMGC0/PMLC bits).
1 PMCs are not incremented. Set by hardware when an interrupt is signalled and FCECE =1.
Performance monitor interrupt enable. Interrupts are caused by PMC overflows.
0 Interrupts are disabled.
1 Interrupts are enabled and occur when an enabled condition or event occurs.
Freeze counters on enabled condition or event. An enabled condition or event is defined as:
The use of the trigger and freeze counter conditions depends on the enabled condition.
0 PMCs can be incremented (if permitted by other control bits).
1 PMCs can be incremented (if permitted by other control bits) only until an enabled condition

or event occurs, at which time PMGC0[FAC] is set. It is up to software to clear FAC.
