Programmable microsequencer

Maturity plannedTargets FPGA + ASICDifficulty EasyPriority 3

Minimal custom-ISA sequencer with a small instruction RAM for power, test and peripheral sequencing where a full core is unnecessary.

Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
