Preliminary
5.6.16.3 Vector Number - Vector Address Bus (VAB)—Bits 12–6
This
read-only
field shows the vector number (VAB[6:0]) used at the time the last IRQ was taken. In the
case of a Fast Interrupt, it shows the lower address bits of the jump address. This field is only updated when
the 56800E core jumps to a new interrupt service routine.
Note:
Nested interrupts may cause this field to be updated before the original interrupt service routine can
read it.
5.6.16.4 Interrupt Disable (INT_DIS)—Bit 5
This bit allows all interrupts to be disabled.
0 = Normal operation (default)
1 = All interrupts disabled
5.6.16.5 Reserved—Bits 4–2
This bit field is reserved or not implemented. It is read as 1 and cannot be modified by writing.
5.6.16.6 Reserved—Bits 1–0
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
