• Description: (MC56F8167 / MC56F8367) 16-bit Digital Signal Controllers
• Manufacturer: Freescale Semiconductor

5.6.30.3
This read-only field shows the vector number (VAB[7:1]) used at the time the last IRQ was taken. This
field is only updated when the 56800E core jumps to a new interrupt service routine.
Note:
5.6.30.4
This bit allows all interrupts to be disabled.
5.6.30.5
This bit field is reserved or not implemented. It is read as 1 and cannot be modified by writing.
5.6.30.6
This read-only bit reflects the state of the external IRQB pin.
5.6.30.7
This read-only bit reflects the state of the external IRQA pin.
5.6.30.8
This bit controls whether the external IRQB interrupt is edge- or level-sensitive. During Stop and Wait
modes, it is automatically level-sensitive.
5.6.30.9
This bit controls whether the external IRQA interrupt is edge- or level-sensitive. During Stop and Wait
modes, it is automatically level-sensitive.
5.6.31
5.6.32
Note: This register is NOT available in the 56F8167 device.

Base + $1F
RESET
0 = Normal operation (default)
1 = All interrupts disabled
0 = IRQB interrupt is a low-level sensitive (default)
1 = IRQB interrupt is falling-edge sensitive
0 = IRQA interrupt is a low-level sensitive (default)
1 = IRQA interrupt is falling-edge sensitive

Nested interrupts may cause this field to be updated before the original interrupt service routine can
read it.
