3.5.2 System Power Management Status and Control 2 Register
(PMC_SPMSC2)
This register is used to report the status of the low-voltage warning function, and to
configure the stop mode behavior of the MCU. This register should be written during the
user's reset initialization program to set the desired controls, even if the desired settings
are the same as the reset settings.
