Memory Address Control. The Memory Address Control controls the addresses
used to read waveform memory data.
This block loads the first address of the waveform into the Address Counter that
was loaded into the waveform memory. It loads the waveform data length to the
Length Counter. The Address Counter specifies the point from which the
waveform was generated, and the Length Counter waveform ending position.
The Address and Length Counters operate with clocks produced by quarter
frequency-division for the clocks from the clock oscillator.
If the repeat count value has been loaded in the Repeat Counter, the waveform is
generated the specified number of times.
This block controls the sequence to the event signals generated in Enhanced
Mode.
