Revision 1.94
The SN8P1600 highly performs the dual clock micro-controller system. The dual clocks are high-speed clock and
low-speed clock. The high-speed clock frequency is supplied through the external oscillator circuit. The low-speed
clock frequency is supplied through on-chip RC oscillator circuit.
The external high-speed clock and the internal low-speed clock can be system clock (Fosc). The system clock is
divided by 4 to be the instruction cycle (Fcpu).
Fcpu = Fosc / 4
The system clock is required by the following peripheral modules:
