MOD 54415 Adress/Databus Pins dirctly connected?
Posted: Wed Sep 24, 2014 6:25 am
Hello,
I have switched from MOD5234 to MOD54415. It becomes not clear to me, if the Adress/Data Pins are directly connected to the CPU or they are latched.
If the reference manual is the following statement:
"An address bus latch is included on the MOD54415 so you do not need to add an external latch"
From the MOD54415, I get the impression, all Flexbus data/adress pins are connected directly to the CPU, because the corresponding pin are listed.
Background:
I have to design a memory interface within a Xilinx FPGA and need more informations about the pin functions. If the AdressLatchEnableSignal would be available, I could realize a real 32bit wide interface.
Kind regards
Reinhard
