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
f

The operating range for f
OSC
can be set with bit 1 of system selection register 1 (SSR1: $027).
2. The oscillation stabilization time is the period required for the oscillator to stabilize in the
following situations:
