Channel n Interrupt Status Bit:
This READ-ONLY bit-field indicates whether the XRT75R12 has a
pending Channel n-related interrupt that is awaiting service. The last
six channels are serviced through this location and the other six at
address 0x61. These two registers are used by the Host to identify the
source channel of an active interrupt.
0 - Indicates that there is NO Channel n-related Interrupt awaiting ser-
vice.
1 - Indicates that there is at least one Channel n-related Interrupt await-
ing 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 n
(Address Locations = 0xn2) to determine the exact source of the inter-
rupt request.
NOTE: Once this bit-field is set to "1", it will not be cleared back to "0"
until the user has read out the contents of the Source-Level
Interrupt Status Register bit, that corresponds to the interrupt
request channel.
