Reserved
This bit is always read as 1 and cannot be modified.
Reserved
These bits are always read as 0 and cannot be modified.
Mode Select 2 and 1
These bits indicate the input levels at pins MD2 and MD1
(the current operating mode). Bits MDS2 and MDS1
correspond to MD2 and MD1, respectively. MDS2 and
MDS1 are read-only bits and they cannot be written to.
The mode pin (MD2 and MD1) input levels are latched
into these bits when MDCR is read. These latches are
canceled by a reset. These latches are canceled by a
reset.
