Hi Ueda-san,
Current flows based on the following:
nSLEEP high
nRESET high
xENBL high
xVREF voltage
If xVREF is low (0V), current should flow for the blanking time as a minimum.
If xVREF is open, current should flow for the blanking time as a minimum. After that it is hard to predict because this is a high impedance path.
If xVREF is high (3.3V), current should flow until the voltage across the sense resistor meets Equation 1 times the relative current percentage in Table 2.
