NOTES:
This allows connection to a BVM Memory Module. # indicates a direct connection to the
equivalent processor signal, see the MC68040 and MC68060 manual or data sheet for an
explanation. /RST is a general reset signal, /MIRQ is an interrupt signal from the module,
and MERR is a bus error signal from the module. The 12 volt power connection is not
switched, and is intended for FLASH memory programming on those modules that
support it. The 5 volt standby power supply is connected directly to the 5STDBY
line, and is intended for non-volatile SRAM backup on those modules that support it.
The interface is not intended for user connection, the pinout is provided here for reference
only.
Some memory modules provide a JTAG programming strip to allow direct programming from the host
module. This connector detail is known as M4, the connections are shown below, and are
for factory
use only
.
