3.2.21：Flash Address Alignment

When adding firmware, the following prompt may appear:

The bytes that need to be aligned when the target chip writes Flash are related to the minimum unit of Flash writing in the chip manual, and generally do not affect the program. For example, the minimum unit for writing Flash is to write at least 4 bytes at a time, and the firmware has 7 bytes in total, so the PowerWriter client will fill 1 byte, and the filled data is the value after the chip is erased, generally 0xff.
