5.6.25 Interrupt Priority Register 14
5.6.26 Software Trigger Interrupt Register
The IPR14 register controls the priority of four peripheral interrupts. Each interrupt can
have one of 32 priorities, where 0 is the highest priority.
Table 87.
The STIR register provides an alternate way for software to generate an interrupt, in
addition to using the ISPR registers. This mechanism can only be used to generate
peripheral interrupts, not system exceptions.
By default, only privileged software can write to the STIR register. Unprivileged software
can be given this ability if privileged software sets the USERSETMPEND bit in the ARM
Cortex-M3 CCR register.

Software Trigger Interrupt Register (STIR - address 0xE000 EF00) bit description
All information provided in this document is subject to legal disclaimers.
Description
These bits ignore writes, and read as 0.
PIO0 Interrupt Priority. 0 = highest priority. 31 (0x1F) = lowest priority.
Reserved, user software should not write ones to reserved bits. The
value read from a reserved bit is not defined.
Description
Writing a value to this field generates an interrupt for the specified the
interrupt number (see
0 to 56.
Reserved, user software should not write ones to reserved bits. The
value read from a reserved bit is not defined.
