    Switching between UART and I2C mode on Cy7C65215

    user_25538177

      I would like to switch between UART mode (SBC0 Mode 2) and I2C modes (SBC0 Mode 5/6). Is there a command to switch at runtime, or does it require reprogramming the internal flash?

       

      If flash reprogramming is required:

      1) How many cycles does the flash endure?

      2) Reading and writing of the flash is apparently possible using the READ/WRITE_USER_FLASH requests, (0xE0, 0xE1). Can you provide a config suitable for the CyUSB3Kit-003, changing the SBC0 config from UART mode to I2C mode?
