CubeSuite+ V2.01.00 CHAPTER 4 ASSEMBLY LANGUAGE SPECIFICATIONS (3) ES and CS registers The ES and CS registers were added for the RL78 family, 78K0R microcontrollers. The ES register specifies the high-order address byte for data instructions, and the CS register specifies the high-order address byte for branch instructions. See "(2) Addressing of data addresses" for more information about how to use the ES register, and see "(1) Addressing of instruction addresses" for more information about how to use the CS register. On reset, ES is set to 0FH and CS is set to 00H Figure 4-14.
