TATUS
Channel 2 Interrupt Status Bit:
This READ-ONLY bit-field indicates whether or not the XRT75R03
has a pending Channel 2-related interrupt that is awaiting service.
0 - Indicates that there is NO Channel 2-related Interrupt awaiting
service.
1 - Indicates that there is at least one Channel 2-related Interrupt
awaiting service. In this case, the user's Interrupt Service routine
should be written such that the Microprocessor will now proceed to
read out the contents of the Source Level Interrupt Status Register
- Channel 2 (Address Location = 0x12) in order to determine the
exact cause of the interrupt request.
