What's the difference between boot mode, user boot mode, and user program mode for flash memory in the 0.18 μm process version?
Boot mode is used for transmitting control commands and write data from a host via SCI or USB, and programming/erasing such commands or data in the user mat and user boot mat. User boot mode is used for executing programs from the user boot area (programs must be preprogrammed into the user boot area during boot mode). User program mode is used for programming/erasing to the user mat using programming/erase control programming created in advance by the MCU's on-chip programming/erase program. In addition, please note that you cannot program/erase to the user boot mat in user program mode.
