... It's RC osc signal. <IrDA mode application note> Since IrDA has strictly protocol when transmit/receive data. We suggest programmers use X’tal to be system clock instead of RC-OSC if IrDA signals are needed. Programmer can use ceramic-OSC to gain some profit since it’ s cheaper than X’ tal. 29/35 ST2601B ...
