Notes: 1. Bits 0 and 1 (SSR10, SSR11) of system clock select register 1 (SSR1: $029) and bit 2 (SSR22)
of system clock select register 2 (SSR2: $02A) must be set according to the system clock
frequency.
2. SEL = 1
3. SEL = 0
4. The oscillation stabilization time is the period required for the oscillator to stabilize after V
reaches 2.7 V (1.8 V for HD404654 and HD404652) at power-on, after
RESET
input goes low
when stop mode is cancelled, or after
STOPC
input goes low when stop mode is cancelled. At
power-on or when stop mode is cancelled,
RESET
or
STOPC
must be input for at least t
to
ensure the oscillation stabilization time. If using a ceramic oscillator, contact its manufacturer to
determine what stabilization time is required, since it will depend on the circuit constants and
stray capacitance.
