STRAP OPTION
10/47
Issue 1.6
Note; Setting of Strap Options MD [15:2] have no effect on theDRAM Controller but are purely meant for software
issues. i.e. Readable in a register.
2.1 Power on strap registers description
2.1.1 Strap register 0 Index 4Ah (Strap0)
Bits 7-0; This register reflect the status of pinsMD[7:0] respectively. They are expected to be connected on the sys-
tem board to the SIMM configuration pins as follows:
Note that the SIMM speed and type information read here is meant only for the
softwareand is not used by the hardware. The software must program the Host and
graphics dram controller configuration registers appropriately based on these
bits.
This register defaults to the values sampled on MD[7:0] pins after reset.
2.1.2 Strap register 1 Index 4Bh (Strap1)
Bits 7-0; This register reflect the statusof pins MD[15:8] respectively. They areexpected to be connected on thesys-
tem board to the SIMM configuration pins as follows:
