To maintain I/O states for pins configured as general-purpose I/O before entering stop2, the user must
restore the contents of the I/O port registers, which have been saved in RAM, to the port registers 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.
3.6.3
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
