set. FSTRD is cleared by Power-up or Local Reset if the
FSTRD bit in the reset serial bit stream is 0. It is set by
Power-up, soft, or Local Reset if the FSTRD bit in the
reset serial bit stream is 1. Note that this bit can also be
read in the Memory Configuration Register.
STATCOL When the STATCOL bit is set, the RACODE and/or
RADATA bits in the Scrub Control Register can be set.
When it is cleared, they cannot. STATCOL is initialized
by Power-up, soft, or Local Reset to match the value of
the STATCOL bit in the reset serial bit stream.
WRHDIS This bit controls a function that is not currently used in the
MCECC.
