3.2.1
Note: * Determined by pins MD
MDCR is an 8-bit read-only register that indicates the current operating mode of the H8S/2339
Group chip.
Bit 7—Reserved: This bit is always read as 1, and cannot be modified.
Bits 6 to 3—Reserved: These bits are always read as 0, and cannot be modified.
Bits 2 to 0—Mode Select 2 to 0 (MDS2 to MDS0): These bits indicate the input levels at pins
MD
MDS2 to MDS0 are read-only bits, and cannot be written to. The mode pin (MD
levels are latched into these bits when MDCR is read. These latches are canceled by a reset.
