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.

MCWOO I i 8-BIT MICROPROCESSING UNIT (MPU) I The MC6800 is a monolithic 8-bit microprocessor forming the central control function for Motorola’s M68~ family. Compatible with TTL, the MC6B~, as with all M6800 system parts, requires only one + 5.O-volt power supply, and no external TTL devices for bus interface. The MC6800 is capable of addressing 64K bytes of memory with its 16-bit address lines. The 8-bit data bus is bidirectional as well as threestate, making direct memory addressing and multi.
