IRQVEC Register
The IRQ interrupt vector register, IRQVEC points to a memory
address containing a pointer to the interrupt service routine of
the currently active IRQ. This register should only be read when
an IRQ occurs and IRQ interrupt nesting has been enabled by
setting Bit 0 of the IRQCONN register.
Name:
IRQVEC
Address:
0xFFFF001C
Default Value:
0x00000000
Access:
Read only

R
0
Highest priority source. This is a
value between 0 and 27 represent-
ing the possible interrupt sources.
For example, if the highest currently
active IRQ is Timer 2, then these bits
are [00100].

Priority Registers
The IRQ interrupt vector register, IRQVEC points to a memory
address containing a pointer to the interrupt service routine of
the currently active IRQ. This register should only be read when
an IRQ occurs and IRQ interrupt nesting has been enabled by
setting Bit 0 of the IRQCONN register.
