MC68B00 - MOTOROLA

MC68B00 8-BIT MICROPROCESSING UNIT

Proper operation of the MPU requires that certain control Read (high) or Wrile (low) state, The normal standby state of and timing signals be provided to accomplish tions and that other signal lines be monitored the state of the processor. (o1, 42) specific functo determine this signal is Read (high). Three-State Control going high will turn Re.
