3.4 Interrupt Enable Register (VICIntEnable - 0xFFFF F010)
3.5 Interrupt Enable Clear Register (VICIntEnClear - 0xFFFF F014)
3.6 Interrupt Select Register (VICIntSelect - 0xFFFF F00C)
Table 105. Raw Interrupt Status register (VICRawIntr - address 0xFFFF F008) bit description
This is a read/write accessible register. This register controls which of the 32 combined
hardware and software interrupt requests are enabled to contribute to FIQ or IRQ.
Table 106. Interrupt Enable register (VICIntEnable - address 0xFFFF F010) bit description
This is a write only register. This register allows software to clear one or more bits in the
Interrupt Enable register (see
0xFFFF F010)” on page
Table 107. Interrupt Enable Clear register (VICIntEnClear - address 0xFFFF F014) bit
This is a read/write accessible register. This register classifies each of the 32 interrupt
requests as contributing to FIQ or IRQ.

Description
When this register is read, 1s indicate interrupt requests or software
interrupts that are enabled to contribute to FIQ or IRQ.
When this register is written, ones enable interrupt requests or
software interrupts to contribute to FIQ or IRQ, zeroes have no
effect. See
(VICIntEnClear - 0xFFFF F014)” on page 113

113), without having to first read it.
Neither the hardware nor software interrupt request with this
bit number are asserted.
The hardware or software interrupt request with this bit
number is asserted.
Writing a 0 leaves the corresponding bit in VICIntEnable
unchanged.
Writing a 1 clears the corresponding bit in the Interrupt
Enable register, thus disabling interrupts for this request.
