MSCAN08 Controller (MSCAN08)
12.7 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:
12.8 Low-Power Modes
In addition to normal mode, the MSCAN08 has three modes with reduced power consumption: sleep, soft
reset, and power down. 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 MSCAN08 wakeup
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
