Note: This register can only be accessed from privileged mode.
The PRIn registers 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:
InterruptPRIn Register Bit Field
Interrupt [4n+3]Bits 31:29
Interrupt [4n+2]Bits 23:21
Interrupt [4n+1]Bits 15:13
Interrupt [4n]Bits 7:5
See Table 2-9 on page 86 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 131) indicates the
position of the binary point that splits the priority and subpriority fields.
These registers can only be accessed from privileged mode.
