// In the case of older generations like PU-7 through PU-20, we are connected to the output of an operational amplifier used as a buffer
//(this part of the motherboard was detailed in the official schematics; by convention, this point was labeled GATE).
//In normal operation, this line is always high, but pulling it down frees the DATA line, allowing the SCEX code to be injected without any further issues.
//
//If we are dealing with PU-22 or newer models, it is connected to a WFCK clock output. This clock signal will be used to synchronize the SCEX injection.
