Read_Register() command
Read_Register(Addr, Status, Data0, Data1, to Datan) allows a block of
bytes to be read in a contiguous memory area starting from the specified address. The
address is auto incremented after each byte.
Write_Buffer() command
Write_Buffer(Offset, Data0, Data1, to Datan) allows transmit packet payload
data to be written to a contiguous data memory area, starting from the specified offset. The
offset is auto incremented after each byte. When the offset exceeds the value 255, it is
wrapped around to 0 (providing a 256-byte circular buffer).
Read_Buffer() command
Read_Buffer(Offset, Status, Data0, Data1, to Datan) allows receive packet
payload data to be read from a contiguous data memory area, starting from the specified
