Endian select registers (MDEB, MDES) [RX71M, RX651, RX65N, RX64M, RX62x, RX630, RX631, RX63N, RX63T, RX634, RX210, RX21A, RX220, RX23x, RX24T, RX110, RX111, RX113, RX130]

2.22.3 Endian select registers (MDEB, MDES) [RX71M, RX651, RX65N, RX64M, RX62x, RX630, RX631, RX63N, RX63T, RX634, RX210, RX21A, RX220, RX23x, RX24T, RX110, RX111, RX113, RX130]

The endian select registers (MDEB, MDES) are such that endian information you set in the [Endian] property in the [Operating Modes of CPU] [E1] [E20] [EZ Emulator] category on the Property panel's [Connect Settings] tab (or the [Endian of CPU] property in the [Endian] [Simulator] category on the Property panel's [Connect Settings] tab for the simulator) is written to the register corresponding to the operation mode in which you perform debugging.

When debugging in single-chip mode, you cannot modify the endian select register S (MDES) in the Memory panel, etc. When debugging in the user boot mode, you cannot modify the endian select register B (MDEB) in the Memory panel, etc.
