Description
Configured Through Boot
Configuration Pins
Bit 0 Mode
-
0 = Host mode (direct boot mode)
1 = Boot table boot mode
Bit 1 Configuration of PCIe
0 = PCIe is configured by RBL
1 = PCIe is not configured by RBL
Bits 3-2 Reserved
Bit 4 Multiplier
0 = SerDes PLL configuration is done based on SerDes register values
1 = SerDes PLL configuration based on the reference clock values
Bits 15-5 Reserved
PCI address width, can be 32 or 64
-
SerDes frequency, in Mbps. Can be 2500 or 5000
-
Reference clock frequency, in units of 10 kHz. Value values are 10000
-
(100 MHz), 12500 (125 MHz), 15625 (156.25 MHz), 25000 (250 MHz), and 31250
(312.5 MHz). A value of 0 means that value is already in the SerDes
configuration parameters and will not be computed by the boot ROM.
