I<4:0> binary code indicates the channel number at which a Tone Detector state
change has occurred.
Note: Whenever a Tone Disable is detected or released, an interrupt is generated.
Reserved bits. Must always be set to zero for normal operation.
Test IRQ: Useful for the application engineer to verify the interrupt service routine.
When high, any change to MTDBI and MTDAI bits of the Main Control Register will
cause an interrupt and its corresponding channel number will be available from the
Interrupt FIFO Register.
When low, normal operation is selected.
