Data Bus Structure
The local data bus on the MVME162 is a
MC68040 or MC68LC040 MPU
The MC68040 or MC68LC040 processor is used on the MVME162. The MC68040 has
MC68xx040 Cache
The MVME162 local bus masters (VMEchip2, MC68xx040, 53C710 SCSI controller, and 82596CA Ethernet controller) have programmable control of the snoop/caching mode. The MVME162 local bus slaves which support MC68xx040 bus snooping are defined in the Local Bus Memory Map table later in this chapter.
No-VMEbus-Interface Option
The MVME162 can be operated as an embedded controller without the VMEbus interface. To support this feature, certain logic in the VMEchip2 has been duplicated in the MCchip. This logic is inhibited in the MCchip if the VMEchip2 is present. The enables for these functions are controlled by software and MCchip hardware initialization.
