This section details the GPIOs and boot option
values used for boot mode set in the BOOT_DEF memory location located at
Z1-OTP-BOOTDEF-LOW/ Z2-OTP-BOOTDEF-LOW and Z1-OTP-BOOTDEF-HIGH/ Z2-OTP-BOOTDEF-HIGH.
Refer to Configuring Boot
Mode Table Options on how to configure BOOT_DEF. When selecting a boot
mode option, make sure to verify that the necessary pins are available in the pin
mux options for the specific device package being used.
