MISRG consists of three control bits (bits 1 to 3) for middle-speed
mode automatic switch and one control bit (bit 0) for oscillation
stabilizing time set after STP instruction released.
By setting the middle-speed mode automatic switch start bit to
1
while operating in the low-speed mode and setting the middle-
speed mode automatic switch set bit to
1
, X
IN
oscillation
automatically starts and the mode is automatically switched to the
middle-speed mode.
