Table 10-23 describes the CISR0 fields.

10.3.3.4 Critical Interrupt Summary Register 1 (CISR1)

Figure 10-19 shows CISR1.

Table 10-24 describes CISR1 register.

10.3.4 Performance Monitor Mask Registers (PMMRs)

There are four pairs of performance monitor mask registers, PMnMR0 and PMnMR1. Each pair

can be configured to select one interrupt source (interprocessor, timer, message, external, or

internal) to generate a performance monitor event. The performance monitor can be configured to

track this event in the performance monitor local control registers. See Section 19.3.2.2,

“Performance Monitor Local Control Registers (PMLCAn and PMLCBn).”
