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
MVME1X2P4 VME 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 MVME162P4. There are two slave address decoders set. They are set up as follows:
Slave Enable #1 [Y/N] Y Yes, set up and enable 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.
Slave Ending Address #1 000FFFFF Ending address of the local resource that is
accessible by the VMEbus. Default is the end
of calculated memory.
Slave Address Translation
Address #1 00000000 This register allows the VMEbus address and
the local address to differ. The value in this
register is the base address of the local resource
that is associated with the starting and ending
address selection from the previous questions.
Default is 0.
Slave Address Translation Select
#1 00000000 This register defines which bits of the address
are significant. A logical "1" indicates
significant address bits, logical "0" is non-
significant. Default is 0.
Slave Control #1 03FF Defines the access restriction for the address
space defined with this slave address decoder.
Default is $03FF.
Slave Enable #2 [Y/N] N Do not set up and enable Slave Address
Decoder #2.
Slave Starting Address #2 00000000 Base address of the local resource that is
accessible by the VMEbus. Default is 0.
Slave Ending Address #2 00000000 Ending address of the local resource that is
accessible by the VMEbus. Default is 0.
Slave Address Translation
Address #2 00000000 Works the same as Slave Address Translation
Address #1. Default is 0.
