SN8P1602B
8-Bit Micro-Controller
OVERVIEW
The SN8P1602B is a dual clock micro-controller system. There are external high-speed clock and internal low-speed
clock. The high-speed clock is generated from the external oscillator circuit. The low-speed clock is generated from
on-chip RC oscillator circuit.
Both 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
