The interrupt enable register is used by the external processor to mask unnecessary interrupt sources. Bits
loaded with a 1 allow the corresponding interrupt condition to generate an interrupt on the external terminal.
Conversely, bits loaded with a 0 mask the corresponding interrupt condition from generating an interrupt on
the external terminal. This register only affects the external terminal, it does not affect the bits in the interrupt
status register. A given condition can set the appropriate bit in the status register and not cause an interrupt
on the external terminal. To determine if this device is driving the interrupt terminal, check either the interrupt
status register with the interrupt enable register or check the state of the interrupt bit in the interrupt
configuration register.

Interrupt Polarity
0 = Interrupt is active low.
1 = Interrupt is active high.
Interrupt
0 = Interrupt terminal is not
active.
1 = Interrupt terminal is
active.
Reflects state of interrupt
terminal.
YUV output
enable
0 = YUV terminals are high
impedance.
1 = YUV terminals are active.
The interrupt configuration register configures the polarity of the external interrupt terminal.
2.15.44 Interrupt Status Register
VIP address
NA
VMI address
