Peripheral Usage in Sleep

Some peripherals that can operate in Sleep mode will not operate properly with the Low-Power Sleep mode selected. The Low-Power Sleep mode is intended for use with these peripherals:

It is the responsibility of the end user to determine what is acceptable for their application when setting the VREGPM settings in order to ensure operation in Sleep.

Important: The PIC18F27/47K40 devices do not have a configurable Low-Power Sleep mode. PIC18LF27/47K40 devices are unregulated and are always in the lowest power state when in Sleep, with no wake-up time penalty. These devices have a lower maximum VDD and I/O voltage than the PIC18F27/47K40.
