Board Level Hardware Description

The access timer logic is duplicated in the VMEchip2 and MCchip ASICs. Because the local bus timer in the VMEchip2 can detect an offboard access and the MCchip local bus timer cannot, the timer in the VMEchip2 is used in all cases except for the version of the MVME162 which does not include the VMEbus interface ("No-VMEbus-Interface option").

Local Bus Arbiter

The local bus arbiter implements a fixed priority which is described in the following table.

Table 1-2. Local Bus Arbitration Priority

Device	Priority	Note


LAN	0	Highest

SCSI	1	...

VMEbus	2	Next Lowest

MC68xx040	3	Lowest

Connectors

The MVME162 has two 96-position DIN connectors: P1 and P2. P1 rows A, B, C, and P2 row B provide the VMEbus interconnection. P2 rows A and C provide the connection to the SCSI bus, serial ports, and Ethernet. The MVME162 has a 20-pin connector J4 mounted behind the front panel. When the MVME162 board is enclosed in a chassis and the front panel is not visible, this connector allows the reset, abort, and LED functions to be extended to the control panel of the system, where they are visible. The serial ports on the MVME162 are also connected to two 25-pin DB-25 female connectors J9 and J15 on the front panel. The four IPs connect to the MVME162 by four pairs of 50-pin connectors. Four 50-pin connectors behind the front panel are for external connections to IP signals. The memory chip mezzanine board is plugged into two 40-pin connectors.

Memory Maps

There are two points of view for memory maps: 1) the mapping of all resources as viewed by local bus masters (local bus memory map), and 2) the mapping of onboard resources as viewed by VMEbus Masters (VMEbus memory map).

The memory and I/O maps which are described in the following tables are correct for all local bus masters. There is some address translation capability in the VMEchip2. This allows multiple MVME162s on the same VMEbus with different virtual local bus maps as viewed by different VMEbus masters.
