Abstract
An improvement in a microprocessor permitting the selection of write-back, write-through or write-once protocols is disclosed. A pin is connected to either ground or Vcc potential to select either the write-through or write-back protocols. When this pin is connected to the read/write line, the write-once protocol is selected. Interconnection between two processors is described which permits the processors to operate in a write-once protocol with a minimum of glue logic.
