Bits indicating the current
operating mode
Bits 7 and 6—Reserved: Read-only bits, always read as 1.
Bits 5 to 3—Reserved: Read-only bits, always read as 0.
Bits 2 to 0—Mode Select 2 to 0 (MDS2 to MDS0): These bits indicate the logic levels at pins
MD₂ to MD₀ (the current operating mode). MDS2 to MDS0 correspond to MD₂ to MD₀. MDS2
to MDS0 are read-only bits. The mode pin (MD₂ to MD₀) levels are latched when MDCR is read.
