MDCR is an 8-bit read-only register that indicates the current operating mode of the
H8/3024 Group.
Bits 7 and 6—Reserved: These bits can not be modified and are always read as 1.
Bits 5 to 3—Reserved: These bits can not be modified and are always read as 0.
Bits 2 to 0—Mode Select 2 to 0 (MDS2 to MDS0): These bits indicate the logic levels at pins
MD
MDS0 are read-only bits. The mode pin (MD
