• Clock Embedded PLL clock multiplication circuit Operating clock (PLL clock) can be selected from divided-by-2 of oscillation or one to four times the oscillation (at oscillation of 4 MHz, 4 MHz to 16 MHz). The system can be operated by a sub-clock (rated at 32.768 kHz). Minimum instruction execution time: 62.5 ns (at oscillation of 4 MHz, four times the oscillation clock, operation at VCC of 5.0 V) (Continued) s.
