Interrupt Enable Register. The VICxIntEnable register enables the interrupt
requests by unmasking the interrupt sources. On reset, all interrupts are
disabled (masked).
IntEnable:
VIC1IntEnClear: 0x800B_0014 - Write Only
VIC2IntEnClear: 0x800C_0014 - Write Only
Interrupt Enable Clear Register. The VICxIntEnClear register clears bits in the
VICxIntEnable register.
VIC1SoftInt: 0x800B_0018 - Read/Write
VIC2SoftInt: 0x800C_0018 - Read/Write

Enables the interrupt request lines:
1 - Interrupt enabled. Allows interrupt request to ARM
Core.
0 - Interrupt disabled.
Clears bits in the VICxIntEnable register. Writing a bit to
“1” clears the corresponding bit in the VICxIntEnable
register. Any bits written to “0” have no effect.
