Remote command:
Number of Bytes ← Data Setup ← Read/Write
Sets the number of bytes you want to trigger on. Maximum 3 bytes are possible.
Remote command:
Bit ← Data Setup ← Read/Write

State ← Data Setup ← Read/Write
Toggles the logic state of the selected bit: 0 (low), 1 (high), or X (don't care).

C Label List
Label lists are protocol-specific. An I

C PTT file contains three values for each address:
●
"Type": address type, 7-bit or 10-bit long
●
"ID / Addr": hexadecimal address value
●
"Symbolic label": name of the address, specifiing its function in the bus network.
