Appendix E: Functional Operation Summary

Sequence Control This block comprises the sequence memory that stores the contents of sequence control, the counters that read out the contents of that memory, and output the actual waveform memory addresses.

For a sequence file, such as that shown in Table E-1, here is what is actually stored in sequence memory.

AAA.WFM actual addresses AAA.WFM data length looping counter value: 3

BBB.WFM actual addresses BBB.WFM data length looping counter value: 16

The sequence memory capacity is in 8 Kbyte steps for handling even complex waveforms.

The AAA.WFM actual addresses are loaded into the address counter, the AAA.WFM data length is loaded into the length counter, and the looping counter value is loaded into the looping counter.

The address and length counters operate with the clock signal from the clock divider frequency divided by 8 (because the waveform memory is partitioned into 8 banks, this circuit uses a 1@8 clock).

When the value set in the looping counter is reached, the sequence memory address counter is incremented and the contents of the next step are read.

When the burst count is set, that value is set in the burst counter and output the required number of times.

Figure E-9 shows the relationship between sequence memory and waveform memory.
