These ports are in the high-impedance state in the serial PROM mode. The input level is fixed to
the port inputs with a hardware feature to prevent overlap current. (The port inputs are invalid.) To
make the port inputs valid, set the pin of the SPCR register to “1” by the RAM loader control program.
