Channel 1 Interrupt Enable Bit:
This READ-ONLY bit-field indicates whether or not the XRT75R03
has a pending Channel 1-related interrupt that is awaiting service.
0 - Indicates that there is NO Channel 1-related Interrupt awaiting
service.
1 - Indicates that there is at least one Channel 1-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 1 (Address Location = 0x0A) in order to determine the
exact cause of the interrupt request.
N
Channel 0 Interrupt Enable Bit:
This READ-ONLY bit-field indicates whether or not the XRT75R03
has a pending Channel 0-related interrupt that is awaiting service.
0 - Indicates that there is NO Channel 0-related Interrupt awaiting
service.
1 - Indicates that there is at least one Channel 0-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 0 (Address Location = 0x02) in order to determine the
exact cause of the interrupt request.

Part Number ID Value:
This READ-ONLY register contains a unique value that
represents the XRT75R03. In the case of the XRT75R03,
this value will always be 0x73.
"0" until the user has read out the contents of the Source-
Level Interrupt Status Register bit, that corresponds with
the interrupt request.
"0" until the user has read out the contents of the Source-
Level Interrupt Status Register bit, that corresponds with
the interrupt request.
