To request forced shut down, the GOM bit must be cleared to 0 immediately
after the EFSD bit has been set to 1. If access to another register (including
reading the CnGMCTRL 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.
The GOM bit is cleared only in the initialization mode.
