Abstract
A chained Command/Push/Pull (CPP) bus command is output by a first device and is sent from a CPP bus master interface across a set of command conductors of a CPP bus to a second device. The chained CPP command includes a reference value. The second device decodes the command, in response determines a plurality of CPP commands, and outputs the plurality of CPP commands onto the CPP bus. The second device detects when the plurality of CPP commands have been completed, and in response returns the reference value back to the CPP bus master interface of the first device via a set of data conductors of the CPP bus. The reference value indicates to the first device that an overall operation of the chained CPP command has been completed.
