Notes 1. The reset values of LVIM and LVIS vary depending on the reset source.
2. Regardless of the internal memory capacity, the initial values of the internal memory size switching
register (IMS) and internal expansion RAM size switching register (IXS) of all products in the 78K0/KE2
are fixed (IMS = CFH, IXS = 0CH). Therefore, set the value corresponding to each product as indicated
below.
