R/W 0000
These bits represent the system software interrupt request key. These write-only bits
0000
are executable in both user and privilege modes. A 0x75 written to these bits initiates
IRQ/FIQ interrupts. Data in this field is always read as zero.
R/W 0000
These bits represent the system software interrupt data. The SSDATA bits provide
0000
an 8-bit field that can be used for passing messages into the system software
interrupt.
