4.3 Interrupt Table Entry
The interrupt table contains information about channel-specific events. Its flags are shown
in Figure 4-4. Note that some bits have no meaning when operating in transparent mode.
For more detailed description on which bits are used in HDLC and transparent operation,
refer to Section 2.4, “Channel-Specific Parameters.” Table 4-2 describes the fields of an
interrupt table entry.

Valid bit
0 = Entry is not valid.
1 = Valid entry containing interrupt information.
Upon generating a new entry, the RISC processor sets this bit. The V bit is cleared by the host
immediately after it reads the interrupt flags in this entry (before processing the interrupt). The
V bits in the queue are host-initialized. During the initialization procedure, the host must clear
those bits in all queue entries.
Wrap bit
0 = This is not the last entry in the circular interrupt table.
1 = This is the last circular interrupt table entry. The next event’s entry is written/read (by RISC/
During initialization, the host must clear all W bits in the queue except the last one which must
be set. The length of the queue is left to the user and can be a maximum of 64 Kbytes.
Not idle
0 = No NID event has occurred.
1 = A pattern which is not an idle pattern was identified.
NID interrupts are not generated in transparent mode.
