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) of all products in the 78K0/LC3 are fixed (IMS = CFH). Therefore, set the value
corresponding to each product as indicated below.
