A non-overlapping clock generator that has its dead time adjustable without a complete re-design and re-fabrication. Certain terminals of certain devices of the non-overlapping clock generator are connected only by metal layers. This allows the circuit of the non-overlapping clock generator to be changed, adjusting the dead time, by changing only the masks used to fabricate the metal layers. This allows non-overlapping clock generators on wafers that have been partially fabricated to have their dead times altered from the original design.

Programmable delay clock gaters

Apparatus and method for accessing numerous remote registers on an integrated circuit chip using a minimum of interconnect traces. Plural primary nodes are configured in series along a serial data line, each of the plural primary nodes individually selectable according to a primary address presented on the serial data line. In one embodiment, a hierarchical one of the plural primary nodes includes plural secondary registers, each of the plural secondary registers individually selectable according to a secondary address presented on the serial data line. In another embodiment, a hierarchical one of the plural primary nodes includes plural secondary nodes, each of the plural secondary nodes individually selectable according to a secondary address presented on the serial data line. At least one of the plural secondary nodes includes plural tertiary registers, each of the plural tertiary registers individually selectable according to a tertiary address presented on the serial data line.
