NOTE: These processor signals are meant to be representative. The actual shape of the waveforms will be set by the microprocessor used. Verify
that the processor waveforms meet the parameters in “Waveforms” on page 50 to ensure proper operation. The Processor waveforms are not
required to be synchronous to CLK. They are shown that way to clarify the illustration.

1. Load the Write Address Register with 29 dec to load the output holding registers.
2. Enable Carrier Loop Filter Lag Accumulator holding register for reading.
3. Select the MSByte of the output holding register for output.
4. Assert RD low to output data on C0-7. (Must wait for 6 CLKs after loading the holding registers).
5. Select other bytes of holding register by changing A0-2 and asserting RD.
