2.14.12 Interrupt Request Generating Circuit
The interrupt requests as shown in Table 2.14.3 are generated by combination of the following bits; bits 6
and 7 of the caption position register (address 0266
the contents of bits 3 to 7 of the clock run-in detect register after the occurrence of a data slicer interrupt
request.
