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
reset.
