17.8.2 msCAN12 SOFT_RESET Mode
MC68HC912D60A — Rev 3.0
MOTOROLA
NOTE:
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 0 (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 for ensuring 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.
