4 Device Configuration
4.1 Boot Modes
This device supports a variety of boot modes through an internal ROM bootloader. This device does not
support dedicated hardware boot modes; therefore, all boot modes utilize the internal ROM. The input
states of the BOOT pins are sampled and latched into the BOOTCFG register, which is part of the system
configuration (SYSCFG) module, when device reset is deasserted. Boot mode selection is determined by
the values of the BOOT pins
The following boot modes are supported:
• NAND Flash boot
– 8-bit NAND
• NOR Flash boot
– NOR Direct boot (8-bit)
– NOR Legacy boot (8-bit)
– NOR AIS boot (8-bit)
• I2C0 / I2C1 Boot
– EEPROM (Master Mode)
– External Host (Slave Mode)
• SPI0 / SPI1 Boot
– Serial Flash (Master Mode)
– SERIAL EEPROM (Master Mode)
– External Host (Slave Mode)
• UART0 / UART1 / UART2 Boot
– External Host
