External pins BOOTMODE[4:0] select the boot configuration. The values of
BOOTMODE[4:0] are latched during the low period of RESET. Table 10–1 lists
all the values for BOOTMODE[4:0] as well as the associated memory maps
and boot processes. For example, the value 00000b on BOOTMODE[4:0] se-
lects memory map 0 and indicates that the memory type at address 0 is syn-
chronous DRAM organized as four 8-bit-wide banks and that no boot process
is selected. SDWID is a bit in the EMIF SDRAM control register.
