13.4.2 Channel Underrun Status Output
Figure 106 below shows an example of the channel underrun status being
reported on the CGC Interface. In the example the line number is 3, the
channel pair is 7 (channels 14 and 15), and the high channel (channel 15) is in
underrun while the low channel (channel 14) is in normal mode. These values
are encoded into the 4 data words following the format shown in Table 27.
Status is only reported when a channel enters or exits underrun.
