CBEIF, PVIOL, and ACCERR bits are readable and writable, CCIF and BLANK bits are readable but not
writable, remaining bits read 0 and are not writable in normal mode. FAIL is readable and writable in
special mode. FAIL must be clear when starting a command write sequence. DONE is readable but not
writable in special mode.
