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 fixed (IMS = CFH, IXS = 0CH), regardless of the internal
memory capacity. Therefore, after a reset is released, be sure to set the following values for each
product.
