[ xxh ] will be used to denote this. all commands and some data are sent by using this format. 2. ascii hex format - each nibble of the byte is converted to ascii cod e and sent as a byte. [ xxah ] will be used to denote this. for example, the hex byte 5ah is transmitted in tw o bytes, 35h and 41h . the ascii value for 5 is 35h and the ascii value for a is 41h . all addresses and most data are sent using this fo rmat. address a one byte value ranging from 01h to ffh representi ng the 255 memory.
