[MISRG (MISRG)] 0038
16
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.

Notes 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”.
