Detailed Description

Bootloader command structure for UART (64-bit / 8-byte protocol).

Format: [SYNC(0x55)] [DEVICE_ADDR] [COMMAND] [VALUE(32 MSB first)] [CRC8]

No bit-flipping (unlike SPI). CRC-8 checksum with polynomial x^8 + x^2 + x^1 + x^0. Serialization is handled automatically by the TMC9660Bootloader::sendCommand() methods.
