Writing a bit to “1” generates a software interrupt for the
corresponding source interrupt before interrupt masking.
Writing a bit to “0” has no effect.
Clears bits in the VICxSoftInt register. Writing a bit to “1”
clears the corresponding bit in the VICxSoftInt register.
Writing a bit to “0” has no effect.
