13.4.4.5 Security Modes
The MSCAN module has no security features.
13.4.5 Low-Power Options
If the MSCAN is disabled (CANE=0), the MSCAN clocks are stopped for power saving.
If the MSCAN is enabled (CANE=1), the MSCAN has two additional modes with
reduced power consumption, compared to normal mode: sleep and power down mode. In
sleep mode, power consumption is reduced by stopping all clocks except those to access
the registers from the CPU side. In power down mode, all clocks are stopped and no
power is consumed.
This table summarizes the combinations of MSCAN and CPU modes. A particular
combination of modes is entered by the given settings on the CSWAI and SLPRQ/
SLPAK bits.
For all modes, an MSCAN wakeup interrupt can occur only if the MSCAN is in sleep
mode (SLPRQ=1 and SLPAK=1), wakeup functionality is enabled (WUPE=1), and the
wakeup interrupt is enabled (WUPIE=1).
