This section explains the default boot modes, as well as all the available boot modes supported on this device. The boot ROM uses the boot mode select, general purpose input/output (GPIO) pins to determine the boot mode configuration.
Table 4-3 shows the boot mode options available for selection by the default boot mode select pins. Users have the option to program the device to customize the boot modes selectable in the boot-up table as well as the boot mode select pin GPIOs used.
All the available boot modes on the device are described in Table 4-3.
Boot Mode | GPIO24 (Default boot mode select pin 1) |
GPIO32 (Default boot mode select pin 0) |
---|---|---|
Parallel IO | 0 | 0 |
SCI / Wait Boot(1) | 0 | 1 |
CAN | 1 | 0 |
Flash | 1 | 1 |
All the peripheral boot modes that are supported use the first instance of the peripheral module (SCIA, SPIA, I2CA, CANA, and so forth). Whenever these boot modes are referred to in this chapter, such as SCI boot, it is actually referring to the first module instance, which means the SCI boot on the SCIA port. The same applies to the other peripheral boots.
