As shown in
run mode.
16.4.5.2
The WAI 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 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).
16.4.5.3
The STOP instruction puts the MCU in a low power consumption stand-by mode. In stop mode, the
MSCAN is set in power down mode regardless of the value of the SLPRQ/SLPAK and CSWAI bits
(Table
16.4.5.4
This is a non-power-saving mode. Enabling the MSCAN puts the module from disabled mode into normal
mode. In this mode the module can either be in initialization mode or out of initialization mode. See
Section 16.4.4.5, “MSCAN Initialization
