Notes 1: The microcomputer can be switched to the middle-speed mode automatically by the
SCL/SDA interrupt during operation in the low-speed mode.
2: When switching from the low-speed mode to the middle-speed mode, the value of the
CPU mode register also changes.

sNotes on middle-speed mode switch set bit
When the middle-speed mode automatic switch set bit is set to “1”
during operation in the low-speed mode, XIN oscillation starts au-
tomatically by detecting the rising edge or the falling edge of the
SCL pin or the SDA pin and the microcomputer switch to the
middle-speed mode. Select the timing which switch from the low-
speed mode to the middle-speed mode by the middle-speed mode
automatic switch wait time set bit. The timing which changes from
the low-speed mode by the middle-speed mode automatic switch
wait time set bit. Select according to the oscillation start character-
istic of the oscillator of XIN to be used. By writing “1” in the
middle-speed mode automatic switch start bit during operation in
the low-speed mode, XIN oscillation starts automatically and the
microcomputer changes to the middle-speed mode.
