ABSTRACT:
A low power, single master, variable clock rate, daisy-chainable, serial bus connects a bus dispatch (master) to a chain of one or more daisy-chained peripheral devices (slaves). The bus has a bidirectional serial data line, a bidirectional clock line, unidirectional interrupt line, power and ground lines. Each peripheral device includes a plurality of serial bus support structures. For example, the serial bus support structures can include an interrupt generation circuit, a power-on circuit, and a wake-up interrupt generation circuit, and a wake-up interrupt propagation circuit.
