Notes: 1. Be sure to set system clock selection register (SSR) bits SSR1 and SSR0 to match the system
clock oscillator frequency.
2. Applies to voltage ranges V
CC
= 3.5 to 5.5 V for the HD4074629.
3. There are three oscillator stabilization times.
(1) At power on, the time between the point where V
CC
reaches 2.7 V and the point where
oscillation has stabilized.
(2) At clearing stop mode, the time between the point where the RESET pin reaches the high
level and the point where oscillation has stabilized.
(3) At clearing stop mode, the time between the point where the
STOPC
pin reaches the low level
and the point where oscillation has stabilized.
At power on or when stop mode is cleared, RESET or
STOPC
must be input for at least t
RC
to
ensure the oscillation stabilization time.
Since the oscillator stabilization time will depend on circuit constants and stray capacitances,
determine the oscillator by consulting with the oscillator’s manufacturer.
Be sure to set miscellaneous register (MIS) bits MIS1 and MIS0 to match the system clock
oscillator stabilization time.
4. Refer to figure 108.
5. Refer to figure 109. The t
unit applies when the MCU is in standby or active mode.
The t
subcyc
unit applies when the MCU is in watch or subactive mode.
6. Refer to figure 110.
7. Refer to figure 111.
