Reserved
These bits are always read as 0 and cannot be
modified.
Mode Select 2 to 0
These bits indicate the input levels at pins MD2 to
MD0 (the current operating mode). Bits MDS2 to
MDS0 correspond to MD2 to MD0. MDS2 to MDS0
are read-only bits and they cannot be written to. The
mode pin (MD2 to MD0) input levels are latched into
these bits when MDCR is read.
These latches are canceled by a power-on reset, but
maintained at manual reset.
