During reset signal generation or oscillation stabilization time wait, only the PC contents among the
hardware statuses become undefined. All other hardware statuses remain unchanged after reset.
When a reset is executed in the standby mode, the pre-reset status is held even after reset.
The initial values of the internal memory size switching register (IMS) and internal expansion RAM size
switching register (IXS) after a reset release are constant (IMS = CFH, IXS = 0CH) in all the 78K0/KE2
products, regardless of the internal memory capacity. Therefore, after a reset is released, be sure to set
the following values for each product.
The ROM and RAM capacities of the products with the on-chip debug function can be debugged
according to the debug target products. Set IMS and IXS according to the debug target products.
