immediately following write access after the EFSD bit has been set to 1. If access
to another register (including reading the C0GMCTRL register) is executed
without clearing the GOM bit immediately after the EFSD bit has been set to 1,
the EFSD bit is forcibly cleared to 0, and the forced shutdown request is invalid.
EFSD bit is set (to 1).
Forced shut down by GOM = 0 disabled.
Forced shut down by GOM = 0 enabled.
CAN module is disabled from operating.
