Internal memory size switching register
Internal expansion RAM size switching register
Processor clock control register
The reset values of LVIM and LVIS vary depending on the reset source.
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) are fixed (IMS = CFH, IXS = 0CH).
Therefore, be sure to set IMS to C4H and IXS to 08H.
