sNotes on middle-speed mode automatic
switch set bit
When the middle-speed mode automatic switch set bit is set to “1”
while operating in the low-speed mode, by detecting the rising/fall-
ing edge of the SCL or SDA pin, XIN oscillation automatically starts
and the mode is automatically switched to the middle-speed
mode. The timing which changes from the low-speed mode to the
middle-speed mode can be set as 4.5 to 5.5 cycle, or 6.5 to 7.5
cycle in the low-speed mode by the middle-speed mode automatic
switch waiting time set bit. Select according to the oscillation start
characteristic of the XIN oscillator to be used.

Note:When the mode is automatically switched from the low-speed mode to
the middle-speed mode, the value of CPU mode register (address 003B16)
changes.
