DESCRIPTION
1 = Mask interrupt.
Default value is 1 (masked)
Interrupt mask.
0 = Do not mask interrupt.
1 = Mask interrupt.
Default value is 1 (masked)
23.2 SECONDARY INTERRUPTS
The following sections define the secondary interrupt status and control bits associated with each of
the primary interrupt bits defined in Table 64.
23.2.1 POWER STATE INTERRUPT
The primary PS_INT interrupt comprises three secondary interrupts as described in Section 11.4. The
secondary interrupt bits are defined in Table 65.
Each of the secondary interrupts can be masked. When a mask bit is set, the corresponding interrupt
event is masked and does not trigger a PS_INT interrupt. The secondary interrupt bits in R16402
(4012h) are valid regardless of whether the mask bit is set. The secondary interrupts are all masked
by default.

23.2.2 THERMAL INTERRUPTS
The primary TEMP_INT interrupt comprises a single secondary interrupt as described in Section 26.
The secondary interrupt bit is defined in Table 66.
