18.2.2.7 Software Interrupt Register (SOFTINT)
SoftInt is the Software Interrupt Register. This register generates software interrupts. Bits [31:0]
correspond to the interrupt number in Table 18-1. Note that interrupt number 1 is the only inter-
rupt souce not associated with a physical hardware interrrupt and is therefore reserved for soft-
ware interrupts. However, software interrupts can be generated using any of the 32 bit
locations in the SOFTINT register. For example, as software interrupt can be generated for
interrupt number 0 to test the interrupt processing of the hardware WDT interrupt.

BITS NAME DESCRIPTION
31:0 SoftInt
Generate Software Interrupt Setting a bit generates a software interrupt for
the specific source interrupt before interrupt masking.
For each bit:
1 = Software Interrupt asserted
0 = Has no effect
