Default: Don’t Care
Definition:
Software Interrupt Register. The VICxSoftInt register is used to generate
software interrupts.
Bit Descriptions:
SoftInt:
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.
VICxSoftIntClear
Address:
VIC1SoftIntClear: 0x800B_001C - Write Only
VIC2SoftIntClear: 0x800C_001C - Write Only
Default: Don’t Care
Definition:
Software Interrupt Clear Register. The VICxSoftIntClear register clears bits in
the VICxSoftInt register.
Bit Descriptions:
SoftIntClear:
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.
VICxProtection
Address:
VIC1Protection: 0x800B_0018 - Read/Write
VIC2Protection: 0x800C_0018 - Read/Write
