The VGUS screen has 256 Byte registers, mainly used for related hardware control operations, which are addressed by byte. The starting address is a single byte for register read/write instructions (0x80, 0x81) and the address range is 0x00~0xff.
The data length (N) is in units of bytes and represents the number of register units read consecutively.
It supports reading and writing multiple registers sequentially.
