Notes: 1. The oscillator stabilization time is the period from when V_CC reaches its minimum allowable
voltage (HD404019R/HD40L4019R: 3.5 V, HD4074019: 4.5 V, HD407L4019: 3.0 V (3.5 V when
V_CC = 3.5 V to 6.0 V)) at power-on until when the oscillator stabilizes, or after RESET goes high
by MCU reset to quit stop mode. At power-on or when recovering from stop mode, apply the
RESET input for more than t_RC to meet the necessary time for oscillator stabilization. When using
a crystal or ceramic oscillator, consult with the crystal oscillator manufacturer since the oscillator
stabilization time depends on the circuit constants and stray capacitance. (See figure 26.)
