AI-generated Summary:
ADC interleaved mode doubles the data sampling rate by alternating conversions between two ADC units on the same input pin, synchronized via a General-Purpose Timer (GPT). Precise 180° phase alignment between ADC cores is critical to avoid spurious signals. Gain and offset mismatches between ADC cores can introduce errors but can be compensated digitally. The method enhances signal processing speed by combining outputs from two ADCs using DMA for efficient data transfer. The setup involves configuring ADC, GPT, and DMAC modules on Renesas RA MCUs, demonstrated with the EK-RA6M5 evaluation kit.

Arm® TrustZone® technology divides RA Family microcontrollers into Secure and Non-Secure partitions, enabling secure application development by isolating memory and resources. Secure code accesses both partitions, while Non-Secure code accesses Secure resources only through Non-Secure Callable (NSC) gateways. Development involves creating separate Secure and Non-Secure projects or a Flat project without TrustZone. The RA Project Generator simplifies project setup, managing security attributes, peripheral access, and debugging configurations. Secure code initializes critical functions and controls access, while Non-Secure code interacts via guarded NSC drivers.
