30.1.2 Features
The EzPort includes the following features:
• Serial interface that is compatible with a subset of the SPI format.
• Able to read, erase and program flash memory.
• Able to reset the micro-controller, allowing it to boot from the flash memory after the
memory has been configured.
30.1.3 Modes of Operation
The EzPort can operate in one of two different modes, enabled or disabled.
• Enabled — When enabled, the EzPort steals access to the flash memory, preventing
access from other cores or peripherals. The rest of the microcontroller is disabled to
avoid conflicts. The flash is configured for NVM Special Mode.
• Disabled — When the EzPort is disabled, the rest of the micro-controller can access
flash memory as normal.
