The I²C-bus format provides 7 and 10 bit addresses (see also in the I²C-bus specification). In Tracii Talk the addresses are always specified in one value although the I²C-bus transmits one byte for the 7 bit addresses and two bytes for the 10 bit addresses. All addresses >=100h are 10 bit addresses (2 bytes), but not all addresses <=FFh are 7 bit addresses, because some combinations in the first bytes are reserved for the 10 bit address format (78h..7Bh). Thus, if you send a message with the addresses 78h..7Bh the address is sent as a 10 bit address (2 bytes). Some other addresses of the I²C-bus are also invalid addresses (e.g. 3h -> see I²C-bus specification). Tracii Talk provides the feature to send also these invalid messages. No warning will be displayed, if an invalid address is specified.
