Method of selective digital serial communications of bit sequences

摘要

The method involves using bit sequences of predefined maximum frame length with address fields of defined bit number for addressing subordinate devices, a control field with a defined bit number and a data field with a maximum bit number. The bit sequence is sent serially by the controlling device and written to the interface, whose memory contents are read back to the controlling device in the same cycle.- DETAILED DESCRIPTION - The controlling device sends blocking signal to the subordinate devices (FB1,FB2) when the memory contents read back do not coincide with the transmitted bit sequences. An INDEPENDENT CLAIM is also included for a circuit for implementing the method and for a test bit generator
