Overview
Description
The Renesas RA6M4 group of microcontrollers (MCUs) uses the high-performance Arm® Cortex®-M33 core with TrustZone®. In concert with the Secure Crypto Engine it offers Secure Element functionality. The integrated Ethernet MAC with individual DMA ensures high data throughput. The RA6M4 is built on a highly efficient 40nm process and is supported by an open and flexible ecosystem concept—the Flexible Software Package (FSP), built on FreeRTOS—and is expandable to use other RTOSes and middleware. The RA6M4 is suitable for IoT applications requiring Ethernet, future proof security, large embedded RAM, and low active power consumption down to 99µA/MHz running the CoreMark® algorithm from Flash.

RA6M4
For CAN exception handling, whether there is any exception or error that CAN not be automatically recovered by CAN controller requires the client to reinitialize and configure CAN module. For example，The product operation process does not shut down the receive interrupt, but CAN automatically shut down.

RA6M4
Hi everyone, I have a custom RA6M4 board that's being undetected via USB when connected to a Windows 10 laptop which means i cant flash the board. I have tried with flash programmer but it stays undetected under COM Port and cant connect. What could i be doing wrong?

RA6M1, RA6M2, RA6M3, RA6T1, RA6M4, RA6M5, RA4M2, RA4M3: Can A/D conversion be performed on other analog input?
Yes. Temperature sensor output and internal reference voltage are selectable at the same time as the analog input of the channel. A/D conversion is performed first for the analog input of the channel, next for the temperature sensor output, and then for the internal reference voltage.
