As soon as the carrier interrupt is occurred,
the content of ROB is transferred to RODR.
Figure 20-3 Carrier Frequency & Pulse of Data
The Table 20-1 shows high and low length of carrier fre-
quency according to CFLS and CFHS. This only shows
when the source clock is selected fMAIN and fMAIN÷22 at
4MHz.
