POWER CONTROL USAGE NOTES

After every reset, PCONP register contains the value that enables all interfaces and peripherals controlled by the PCONP to be
enabled. Therefore, apart from proper configuring via peripheral dedicated registers, user's application has no need to access
the PCONP in order to start using any of the on-board peripherals.
Power saving oriented systems should have 1s in the PCONP register only in positions that match peripherals really used in the
application. All other bits, declared to be "Reserved" or dedicated to the peripherals not used in the current application, must be
cleared to 0.
