... Philips Semiconductors 80C51 8-bit microcontroller family 2 2K/64 OTP/ROM low pin count OSCILLATOR CHARACTERISTICS X1 and X2 are the input and output, respectively inverting amplifier which can be configured for use as an on-chip oscillator. To drive the device from an external clock source, X1 should be driven while X2 is left unconnected. There are no requirements on the duty cycle of the external clock signal, because the input to the internal clock circuitry is through a divide-by-two flip-flop ...
