External clock source
In this external clock mode, a clock signal (square, sinus or triangle) with ~50% duty cycle
has to drive the OSC1 pin while the OSC2 pin is tied to ground.
When the Multi-Oscillator is not used OSCI1 and OSCI2 must be tied to ground, and PB1 is
selected by default as the external clock.
Crystal/ceramic oscillators
In this mode, with a self-controlled gain feature, oscillator of any frequency from 1 to 16 MHz
can be placed on OSC1 and OSC2 pins. This family of oscillators has the advantage of
producing a very accurate rate on the main clock of the ST7. In this mode of the multi-
oscillator, the resonator and the load capacitors have to be placed as close as possible to
the oscillator pins in order to minimize output distortion and start-up stabilization time. The
loading capacitance values must be adjusted according to the selected oscillator.
These oscillators are not stopped during the RESET phase to avoid losing time in the
oscillator start-up phase.
Internal RC oscillator
In this mode, the tunable RC oscillator is used as main clock source. The two oscillator pins
have to be tied to ground.
The calibration is done through the RCCRH[7:0] and RCCRL[6:5] registers.
