MDCR is an 8-bit read-only register that indicates the current operating mode of the H8S/2350

Group.

Bit 7—Reserved: Read-only bit, always read as 1.

Bits 6 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 input levels at pins

MD2 to MD0 (the current operating mode). Bits MDS2 to MDS0 correspond to MD2 to MD0.

MDS2 to MDS0 are read-only bits, they cannot be written to. The mode pin (MD2 to MD0) input

levels are latched into these bits when MDCR is read. These latches are canceled by a power-on

reset, but are retained after a manual reset.
