STRAP OPTION
30/61
Issue 2.2 - October 13, 2000
Note 1; Setting of Strap Options MD [15:2] have
no effect on the DRAM Controller but are purely
meant for software issues. i.e. Readable in a reg-
ister.
Note 2; The settings for these Straps is show in
the table below:
For further details refer to Application Note 1297
3.1 Power on strap registers description
3.1.1 Strap register 0 Index 4Ah (Strap0)
Bits 7-0; This register reflect the status of pins
MD[7:0] respectively. They are expected to be
connected on the system board to the SIMM con-
figuration pins as follows:
Note that the SIMM speed and type information
read here is meant only for the software and is not
used by the hardware. The software must pro-
gram the Host and graphics dram controller con-
figuration registers appropriately based on these
bits.
This register defaults to the values sampled on
MD[7:0] pins after reset.
3.1.2 Strap register 1 Index 4Bh (Strap1)
Bits 7-0; This register reflect the status of pins
MD[15:8] respectively. They are expected to be
connected on the system board to the SIMM con-
figuration pins as follows:
MD38
MD39
MD40
MD41
MD42
MD43
