|
|
|
|
|
|
| |
Base Address of Dynamic Memory | 00000000 | Beginning address of Dynamic |
|
|
| Memory (Parity and/or ECC | |
|
| type memory). It must be a | |
|
| multiple of the Dynamic | |
|
| Memory board size, starting | |
|
| with 0. Default is $0. | |
|
|
| |
Size of Parity Memory | 00100000 | This is the size of the Parity type | |
|
| dynamic RAM mezzanine, if | |
|
| any. The default is the calculated | |
|
| size of the Dynamic memory | |
|
| mezzanine board. | |
|
|
| |
Size of ECC Memory Board #0 | 00000000 | This is the size of the first ECC | |
|
| type memory mezzanine. The | |
|
| default is the calculated size of | |
|
| the memory mezzanine. | |
|
|
| |
Size of ECC Memory Board #1 | 00000000 | This is the size of the second | |
|
| ECC type memory mezzanine. | |
|
| The default is the calculated size | |
|
| of the memory mezzanine. | |
|
|
| |
Base Address of Static Memory | FFE00000 | This is the beginning address of | |
|
| SRAM. The default for this | |
|
| parameter is FFE00000 for the | |
|
| onboard 512KB, or E1000000 for | |
|
| the 2MB SRAM mezzanine. If | |
|
| only 2 MB SRAM is present, it | |
|
| defaults to address 00000000. | |
|
|
| |
Sizeof Static Memory | 00080000 | This is the size of the SRAM type | |
|
| memory present. The default is | |
|
| the calculated size of the | |
|
| onboard SRAM or an SRAM | |
|
| type mezzanine. | |

ENV asks the following series of questions to set up the VMEbus interface for the MVME162 series modules. You should have a working knowledge of the VMEchip2 as given in the MVME162 Embedded Controller Programmer’s Reference Guide in order to perform this configuration. Also included in this series are questions for setting ROM and Flash access time.
The slave address decoders are used to allow another VMEbus master to access a local resource of the MVME162. There are two slave address decoders set. They are set up as follows:
Slave Enable #1 [Y/N] | Y | Yes, set up and enable the Slave |
|
| Address Decoder #1. |
|
|
|
Slave Starting Address #1 | 00000000 | Base address of the local |
|
| resource that is accessible by the |
|
| VMEbus. Default is the base of |
|
| local memory, $0. |
