Note: This register can only be accessed from privileged mode.
The PRIn registers (see also page 147) provide 3-bit priority fields for each interrupt. These registers
are byte accessible. Each register holds four priority fields that are assigned to interrupts as follows:
PRIn Register Bit Field
Bits 31:29
Bits 23:21
Bits 15:13
Bits 7:5
Interrupt
Interrupt [4n+3]
Interrupt [4n+2]
Interrupt [4n+1]
Interrupt [4n]
See Table 2-9 on page 99 for interrupt assignments.
Each priority level can be split into separate group priority and subpriority fields. The PRIGROUP
field in the Application Interrupt and Reset Control (APINT) register (see page 159) indicates the
position of the binary point that splits the priority and subpriority fields .
These registers can only be accessed from privileged mode.
