18.8.2 msCAN12 SOFT_RESET Mode
18.8.3 msCAN12 POWER_DOWN Mode
MC68HC912DT128A — Rev 4.0
MOTOROLA
In SOFT_RESET mode, the msCAN12 is stopped. Registers can still be
accessed. This mode is used to initialize the module configuration, bit
timing, and the CAN message filter. See
Register (CMCR0)
mode.
When setting the SFTRES bit, the msCAN12 immediately stops all
ongoing transmissions and receptions, potentially causing the CAN
protocol violations. The user is responsible to take care that the
msCAN12 is not active when SOFT_RESET mode is entered. The
recommended procedure is to bring the msCAN12 into SLEEP mode
before the SFTRES bit is set.
The msCAN12 is in POWER_DOWN mode when
When entering the POWER_DOWN mode, the msCAN12 immediately
stops all ongoing transmissions and receptions, potentially causing CAN
protocol violations. The user is responsible to take care that the
msCAN12 is not active when POWER_DOWN mode is entered. The
recommended procedure is to bring the msCAN12 into SLEEP mode
before the STOP instruction (or the WAI instruction, if CSWAI is set) is
executed.
To protect the CAN bus system from fatal consequences of violations to
above rule, the msCAN12 will drive the TxCAN pin into recessive state.
In POWER_DOWN mode, no registers can be accessed.
