2.5.1 Boot Device Field
The Boot Device field BOOTMODE[2:0] defines the boot device that is chosen. Table 2-4 shows the supported boot
modes.

Device boot mode
0 = EMIF16 / No Boot
1 = Serial Rapid I/O
2 = Ethernet (SGMII) (PASS PLL configuration assumes input rate same as CORECLK(P|N); BOOTMODE[12:10] values drive
the PASS PLL configuration during boot)
3 = Ethernet (SGMII) (PASS PLL configuration assumes input rate same as SRIOSGMIICLK(P|N); BOOTMODE[9:8] values
drive the PASS PLL configuration during boot)
4 = PCIe
5 = I2C
6 = SPI
7 = HyperLink
End of Table 2-4
Internally this boot mode are translated by RBL into the extended boot mode value that is used in the boot parameter
table. Table 2-5 shows the details of extended boot mode values.
