ABSTRACT:
An integrated circuit includes a programmable servo burst sequencer that includes an instruction memory, an instruction register, and an address control circuit. The instruction register drives a plurality of output lines of the programmable servo burst sequencer. The programmable servo burst sequencer can process a plurality of fields in any one of a plurality of servo sectors. The programmable servo burst sequencer eliminates the need for a specific servo burst sequencer for each possible configuration of the plurality of fields in a servo sector. The user simply uses a plurality of instructions to configure the programmable servo burst sequencer so that the programmed servo burst sequencer can process the plurality of fields in the servo sector information on the user's disk drive.
