pin, for 68 series MPU: input
from the Enable pin, and for the serial interface: input from the SCL pin) during detection of the SVD2
output.
*2: Wait time until SVD2 sampling is enabled after stopping access from MPU. Apply when the temperature
sensor is set to ON beforehand. T o set the temperature sensor to ON after stopping access from MPU,
provide a given output voltage setup time.
*3: Wait time until access from MPU can be started after completion of SVD2 sampling by MPU.
