1. A method for calibration during start-up of a micro controller unit (MCU) device, the method comprising:
- reading, by the MCU device, overlay initialisation data from at least one memory element within an external support device operably coupled to the MCU device; and
configuring memory mapping functionality of the MCU device to map an area of a device memory of the MCU device to an area of the at least one memory element of the external support device in accordance with the overlay initialisation data, wherein an access request for the area of the device memory is re-directed to the area of the at least one memory element of the external support device in response to the area of the device memory being mapped to the area of the at least one memory element of the external support device.

Abstract
A method for enabling calibration during start-up of a micro controller unit device is provided. The method comprises, within the MCU device, reading overlay initialization data from at least one memory element within an external support device operably coupled to the MCU device, and configuring memory mapping functionality of the MCU device to overlay data stored within at least a part of device memory of the MCU device with calibration data stored within the at least one memory element of the external support device in accordance with the overlay initialization data.
