A serial data transfer protocol is provided for the serial transfer of data between a master microprocessor and a plurality of slave microprocessors. The basic advantages of this serial data transfer protocol is that it provides an interrupt-proof protocol which uses only a three-wire interface. In order to achieve these advantages, the protocol must be limited to a transfer interface wherein only the master microprocessor can initiate a communication.
