■OPERATIONAL DESCRIPTION (Continued)
<CE/MODE Pin Function>
The operation of the XC9235/XC9236/XC9237 series will enter into the shut down mode when a low level signal is input to the
CE/MODE pin. During the shutdown mode, the current consumption of the IC becomes 0μA (TYP.), with a state of high
impedance at the Lx pin and V
input to the CE/MODE pin is a CMOS input and the sink current is 0μA (TYP.).

Intermediate voltage can be generated by RM1 and RM2. Please set the value of each R1, R2, RM1, RM2 from
few hundreds kΩ to few hundreds MΩ. For switches, CPU open-drain I/O port and transistor can be used.
