Register 53: Software Trigger Interrupt (SWTRIG), offset 0xF00
Note: Only privileged software can enable unprivileged access to the SWTRIG register.
Writing an interrupt number to the SWTRIG register generates a Software Generated Interrupt (SGI).
See Table 2-9 on page 116 for interrupt assignments.
When the MAINPEND bit in the Configuration and Control (CFGCTRL) register (see page 175) is
set, unprivileged software can access the SWTRIG register.

DescriptionResetTypeNameBit/Field
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

Interrupt ID
This field holds the interrupt ID of the required SGI. For example, a value
of 0x3 generates an interrupt on IRQ3.

3.5 System Control Block (SCB) Register Descriptions
This section lists and describes the System Control Block (SCB) registers, in numerical order by
address offset. The SCB registers can only be accessed from privileged mode.
All registers must be accessed with aligned word accesses except for the FAULTSTAT and
SYSPRI1-SYSPRI3 registers, which can be accessed with byte or aligned halfword or word accesses.
The processor does not support unaligned accesses to system control block registers.
