2. The oscillator stabilization time is the period from when V
reaches 2.7 V (HD407L4818: V
CC
=
3.0 V) at power-on until the oscillator stabilizes. The time required to stabilize the oscillator (t
RC
)
must be obtained. Since t
depends on the ceramic oscillator’s circuit constant and stray
capacitance, consult with the ceramic oscillator manufacturer.
3. See figure 48.
4. See figure 49. The unit t
cyc
is applied when the MCU is in standby mode or active mode.
5. See figure 50.
6. See figure 49. The unit t
is applied when the MCU is in watch mode or subactive mode.

s (when a 32.768-kHz crystal oscillator is used)
7. The analog comparator stabilization time is the period from when D
/D
is placed in analog
input mode until the analog comparator stabilizes and correct data can be read.
8. Applies to HD40L4812, HD40L4814, HD40L4816, and HD40L4818.
9. Applies to HD407L4818.
