run mode.
12.5.5.2
The WAIT instruction puts the MCU in a low power consumption stand-by mode. If the CSWAI bit is set,
additional power can be saved in power down mode because the CPU clocks are stopped. After leaving
this power down mode, the MSCAN restarts its internal controllers and enters normal mode again.
While the CPU is in wait mode, the MSCAN can be operated in normal mode and generate interrupts
(registers can be accessed via background debug mode). The MSCAN can also operate in any of the
low-power modes depending on the values of the SLPRQ/SLPAK and CSWAI bits as seen in
12.5.5.3
The STOP instruction puts the MCU in a low power consumption stand-by mode. In stop1 or stop2 modes,
the MSCAN is set in power down mode regardless of the value of the SLPRQ/SLPAK. In stop3 mode,
power down or sleep modes are determined by the SLPRQ/SLPAK values set prior to entering stop3.
CSWAI bit has no function in any of the stop

‘X’ means don’t care.
For a safe wake up from Sleep mode, SLPRQ and SLPAK must be set to 1 before going into Stop3 mode.
