Kinetis ROM Bootloader
11.1 Chip-Specific Information
This device has various peripherals (UART, I2C, SPI ) supported by the Kinetis ROM
Bootloader. To use an interface for bootloader communications, the peripheral must be
enabled in the BCA, as shown in Table 11-3. If the BCA is invalid (such as all 0xFF
bytes), then all peripherals will be enabled by default.The next table shows the pads used
by the Kinetis ROM Bootloader.
