Middle-speed mode automatic switch set bit
By setting the middle-speed mode automatic switch set bit to “1”
while operating in the low-speed mode, X
IN
oscillation automati-
cally starts and the mode is automatically switched to the
middle-speed mode when defecting a rising/falling edge of the
SCL or SDA pin. The middle-speed automatic switch wait time set
bit can select the switch timing from the low-speed to the middle-
speed mode; either 4.5 to 5.5 machine cycles or 6.5 to 7.5
machine cycles in the low-speed mode. Select it according to os-
cillation start characteristics of used X
IN
oscillator.
The middle-speed mode automatic switch start bit is used to auto-
matically make to X
IN
oscillation start and switch to the
middle-speed mode by setting this bit to “1” while operating in the
low-speed mode.

(Note)
Note 1:
Any one of high-speed, middle-speed or low-speed mode is selected by bits 7 and 6 of the CPU mode register.
When low-speed mode is selected, set port Xc switch bit (b1) to “1”.
2:
When the oscillation stabilizing time set after STP instruction released bit is “0”.
