Abstract
A slave controller formed on a single semiconductor substrate executes a built in control algorithm in response to a command supplied from a master controller. Upon completion of command execution, the controls respond to predetermined information contained within the command by branching internal control operation in accordance with the new command. The controls then suspend a series of operations for executing the new command upon detection of the branch condition. Once the internal state has been changed over, the slave controller sends an instruction to the master controller.
