From PIC® MCU I/O

Note:

For applications that can operate directly from the battery input voltage during Standby mode

and require a higher voltage during normal run mode, the MCP16252 device provides input-to-

output bypass, when disabled. Here, the PIC microcontroller is powered by the output of the

MCP16252. One of the microcontroller's I/O pins is used to enable and disable the MCP16252,

and to control its bias voltage. While in Shutdown mode, the MCP16252 input current is typically

0.6 µA.
