HD404369 Series

Notes: 1. When using the subsystem oscillator (32.768 kHz), one of the following relationships for f

OSC

must be applied.

0.4 MHz

≤ f

OSC ≤ 1.0 MHz or 1.6 MHz ≤ fOSC ≤ 5.0 MHz

The operating range for f

OSC can be set with bit 1 of system clock selection register 1 (SSR1:

$027).

2. The oscillation stabilization time is the period required for the oscillator to stabilize in the

following situations:

a. After V

CC reaches 2.7 V at power-on.

b. After

RESET input goes low when stop mode is cancelled.

c. After

STOPC input goes low when stop mode is cancelled.

To ensure the oscillation stabilization time at power-on or when stop mode is cancelled,

RESET

STOPC must be input for at least a duration of t

RC.

When using a crystal or ceramic oscillator, consult with the manufacturer to determine what

stabilization time is required, since it will depend on the circuit constants and stray capacitance.

3. Refer to figure 84.

4. Refer to figure 85.

5. Refer to figure 86.

6. Refer to figure 87.
