MC68020

Abstract: MC68030 logical caches, the MC68851's jumper can have the following signals connected together: LAS o PAS LBRO o , because some systems may use CLI to qualify the occurrence of CPU space cycles since the MC68851's PAS , existing MC68020 or MC68020/MC68851 system by insertion of a more advanced 32-bit MPU with an on-chip data , and an MC68851, the MC68851 may be left in the system or removed (and replaced with a jumpered header). However, if left in the system, the MC68851 is not accessible to the programmer with the M68000
