68331 output driver types
2003-05-21 by FALE(Leopold Faschalek)
Hi, in the Motorola 68331 user manual is in the mcu pin characteristics table for some pins the type 'Bo'. For example MISO, MOSI, SCK and TxD. The description for this mode states it is an type 'B' output that can operate in an open drain mode. My question: does anyone know the exact output circuit for this type 'Bo' outputs? i.e. is there an internal pull up and which value does it have? thanks in advance Leopold Faschalek ------------------------- Research & Development / Senior Software Developer SkiData AG Untersbergstraße 40 A-5083 Gartenau [P] +43(0)6246/888-0 [F] +43(0)6246/888-7 [e] fale@...
