Internal RC oscillator
This oscillator allows a low cost solution for the main clock of the ST7 using only an internal
resistor and capacitor. Internal RC oscillator mode has the drawback of a lower frequency
accuracy and should not be used in applications that require accurate timing.
In this mode, the two oscillator pins have to be tied to ground.

Reset sequence manager (RSM)
Introduction
The reset sequence manager includes three RESET sources as shown in
●
●
●
These sources act on the RESET pin and it is always kept low during the delay phase.
The RESET service routine vector is fixed at addresses FFFEh-FFFFh in the ST7 memory
map.
