"WebBecause there are 32000 possible places in a 256 Kbit EEPROM — and because 255 is the largest number you can encode in one byte — we need to send this address in two bytes. First we send the Most Significant Byte (MSB) — the first 8 bits in this case. Then we send the Least Significant Byte (LSB) — the second 8 bits. Why? " - Rs232 msb or lsb first
