Description
Vector priority 26 register.
Vector priority 27 register.
Vector priority 28 register.
Vector priority 29 register.
Vector priority 30 register.
Vector priority 31 register.
Vector address register. When an IRQ interrupt occurs, the
Vector Address Register holds the address of the currently
active interrupt.
The following section describes the VIC registers in the order in which they are used in the
VIC logic, from those closest to the interrupt request inputs to those most abstracted for
use by software. For most people, this is also the best order to read about the registers
when learning the VIC.
The VICSoftInt register is used to generate software interrupts. The contents of this
register are ORed with the 32 interrupt requests from the various peripherals, before any
other logic is applied.
The VICSoftIntClear register is a ’Write Only’ register. This register allows software to
clear one or more bits in the Software Interrupt register, without having to first read it.
This is a read only register. This register reads out the state of the 32 interrupt requests
and software interrupts, regardless of enabling or classification.

Description
Do not force the interrupt request with this bit number. Writing zeroes to bits
in VICSoftInt has no effect, see VICSoftIntClear
Force the interrupt request with this bit number.
Description
Writing a 0 leaves the corresponding bit in VICSoftInt unchanged.
Writing a 1 clears the corresponding bit in the Software Interrupt register,
removing any interrupt that may have been generated by that bit.
