EFSD Bit enabling forced shut down
0 Forced shut down by GOM bit = 0 disabled.
1 Forced shut down by GOM bit = 0 enabled.
Caution To request forced shut down, clear the GOM bit to 0 immediately 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 shut down request is invalid.

0 CAN module is disabled from operating.
1 CAN module is enabled to operate.
Caution The GOM bit is cleared to 0 only in the initialization mode or immediately after the EFSD bit is
set to 1.
