In the PD78F0114HD, be sure to pull the P31 pin down after reset to prevent
malfunction.
Regardless of the internal memory capacity, the initial values of internal memory
size switching register (IMS) of all products in the 78K0/KC1+ are fixed (IMS =
CFH). Therefore, set the value corresponding to each product as indicated
below. In addition, set the following values to the internal memory size
switching register (IMS) when using the 78K0/KC1+ to evaluate the program of
a mask ROM version of the 78K0/KC1.
When replacing the PD78F0112H with the PD78F0114HD, note that the area
from 0081H to 0083H in the PD78F0114HD cannot be used.
When replacing the PD78F0113H with the PD78F0114HD, note that the area
from 0081H to 0083H in the PD78F0114HD cannot be used.
When replacing the PD78F0114H with the PD78F0114HD, note that the area
from 0081H to 0083H in the PD78F0114HD cannot be used.
Do not access addresses to which SFRs are not assigned.
Since RESET input makes the SP contents undefined, be sure to initialize the
SP before using the stack.
