Note Indicates only permissible oscillator frequency ranges. Refer to AC Characteristics for instruction execution time.
Request evaluation by the manufacturer of the oscillator circuit mounted on a board to check the oscillator
characteristics.
Caution Since the CPU is started by the high-speed on-chip oscillator clock after a reset release, check the X1
clock oscillation stabilization time using the oscillation stabilization time counter status register (OSTC)
by the user. Determine the oscillation stabilization time of the OSTC register and the oscillation
stabilization time select register (OSTS) after sufficiently evaluating the oscillation stabilization time
with the resonator to be used.
Remark When using the X1 oscillator, refer to 5.4 System Clock Oscillator in the RL78/G12 User’s Manual
Hardware.

High-speed on-chip oscillator frequency is selected by bits 0 to 3 of option byte (000C2H) and bits 0 to 2 of
HOCODIV register.
This only indicates the oscillator characteristics. Refer to AC Characteristics for instruction execution time.
