3.1.3
The H8S/2357 Group has a mode control register (MDCR) that indicates the inputs at the mode pins (MD
system control register (SYSCR) and a system control register 2 (SYSCR2)*
Group. Table 3-3 summarizes these registers.

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/2357 Group.
Bit 7—Reserved: This bit cannot be modified and is always read as 1.
Bits 6 to 3—Reserved: These bits cannot be modified and are always read as 0.
Bits 2 to 0—Mode Select 2 to 0 (MDS2 to MDS0): These bits indicate the input levels at pins MD
operating mode). Bits MDS2 to MDS0 correspond to MD
written to. The mode pin (MD
canceled by a power-on reset, but are retained after a manual reset.*
Note: * Manual reset is only supported in the H8S/2357 ZTAT.
3.2.2
Note: * R/W in the H8S/2390, H8S/2392, H8S/2394, and H8S/2398.
