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