before writing to the PPDACK bit. If the port registers are not restored from RAM before writing to
PPDACK, then the pins will switch to their reset states when PPDACK is written.
For pins that were configured as peripheral I/O, the user must reconfigure the peripheral module that
interfaces to the pin before writing to the PPDACK bit. If the peripheral module is not enabled before
writing to PPDACK, the pins will be controlled by their associated port control registers when the I/O
latches are opened.

Stop1 mode is entered by executing a STOP instruction under the conditions as shown in
of the internal circuitry of the MCU is powered off in stop1, providing the lowest possible standby current.
Upon entering stop1, all I/O pins automatically transition to their default reset states.
Exit from stop1 is performed by asserting the wake-up pins or RESET or IRQ.
In addition, the real-time interrupt (RTI) can wake the MCU from stop1 if enabled.
Upon wake-up from stop1 mode, the MCU starts up as from a power-on reset (POR):
In addition to the above, upon waking up from stop1, the PDF bit in SPMSC2 is set. This flag is used to
direct user code to go to a stop1 recovery routine. PDF remains set until a 1 is written to PPDACK in
SPMSC2.
3.6.4
When the MCU enters any stop mode, system clocks to the internal peripheral modules are stopped. Even
in the exception case (ENBDM = 1), where clocks to the background debug logic continue to operate,
clocks to the peripheral systems are halted to reduce power consumption. Refer to
