The Interrupt Vector Clear Register (INT_VC) holds the interrupt vector for the highest priority pending interrupt when read, and
when written clears all pending interrupts.
Bit [7:0]: Pending Interrupt [7:0]
8-bit data value holds the interrupt vector for the highest priority pending interrupt. Writing to this register clears all pending
interrupts.
