24.7 Protocol Violation Protection
The MSCAN08 will protect the user from accidentally violating the CAN protocol through programming
errors. The protection logic implements the following features:
24.8 Low Power Modes
In addition to normal mode, the MSCAN08 has three modes with reduced power consumption: Sleep, Soft
Reset and Power Down modes. In Sleep and Soft Reset mode, power consumption is reduced by
stopping all clocks except those to access the registers. In Power Down mode, all clocks are stopped and
no power is consumed.
The WAIT and STOP instructions put the MCU in low power consumption stand-by modes. summarizes
the combinations of MSCAN08 and CPU modes. A particular combination of modes is entered for the
given settings of the bits SLPAK and SFTRES. For all modes, an MSCAN wake-up interrupt can occur
only if SLPAK=WUPIE=1.

The receive and transmit error counters cannot be written or otherwise manipulated.
All registers which control the configuration of the MSCAN08 can not be modified while the
MSCAN08 is on-line. The SFTRES bit in the MSCAN08 module control register (see
