The FRZ bit is readable and writable in all modes. In debug mode the
SGFM behaves exactly as it does in user mode except that the LOCK
bit in SGFMCR and SGFMCLKD[6:0] bits are writable.
The EME bit is always readable and only writable when LOCK = 0.
EME places the SGFM in emulation mode, during which the SGFM
BIU will not assert TA or TEA to terminate read bus cycles of the
