Wakeup Pin
The WKUP pin is used to wake the device when it is in the Standby or Sleep operating modes. This pin is
edge sensitive and will wake the device on a rising edge. The WKUP pin must be logic low in order for the
device to re-enter Idle mode after a Sleep wakeup, so it should only be pulsed high to wake up the part.
The WKUP pin operates at a 3.3 V logic level. It has a 35 k
Ω ty
pical pull-down resistor inside the R7101C

x4. Voltages outside of the maximum IO operating voltage range of -0.3 to 4.0
V should not be applied to the WKUP pin. This can cause permanent damage to the device.
If the WKUP pin is not used, it should be left floating or tied to logic low (ground).
