Notes: 1. The oscillator stabilization time is the period up until the time the oscillator stabilizes after V
CC
reaches 4.0 V at power-on, or after RESET goes high. At power-on or stop mode release,
RESET must be kept high for at least t
. Since t
depends on the ceramic oscillator’s circuit
constant and stray capacitance, consult with the manufacturer when designing the reset circuit.
2. The oscillator stabilization time is the period up until the time the oscillator stabilizes after V
reaches 4.0 V at power-on. The time required to stabilize the oscillator (t
) must be obtained.
Since t
depends on the crystal circuit constant and stray capacitance, consult with the
manufacturer.
3. See figure 43.
4. See figure 44. The unit t
cyc
is applied when the MCU is in standby mode or active mode.
5. See figure 45.
6. See figure 44. The unit t
is applied when the MCU is in watch mode or subactive mode.
