RX65N - setting of OFSM registers in vecttbl.c
I noticed that the setting of OFSM registers are performed in vecttbl.c, as in the following: #pragma address __MDEreg = 0xFE7F5D00#pragma address __OFS0reg = 0xFE7F5D04 ... ... const uint32_t __MDEreg = (BSP_PRV_MDE_VALUE & BSP_PRV_BANK_MODE_VALUE);const uint32_t __OFS0reg = BSP_CFG_OFS0_REG_VALUE ...

Videos & Training
The Renesas RX65N Cloud Kit is a cloud communication performance evaluation kit that uses the RX65N microcontroller and can connect via Wi-Fi to Amazon Web Services (AWS). It provides an ideal evaluation environment for developers and supports the start of IoT device development by users.
The kit includes a Wi-Fi communication module, a temperature/humidity sensor, an optical sensor, a 3-axis accelerometer, a USB port for serial communications, and another USB port for debugging. The sensor and other data that is uploaded from the kit to AWS can be observed in the dashboard. The program can also be edited or debugged in Renesas' e² studio integrated development environment (IDE), by connecting the kit to a PC.
