Processing device

A processing device comprising:

• a processor;
• and
• a memory including a plurality of storage areas each storing a setting value for a plurality of functions, wherein the processor
• performs predetermined processing by using each of the setting values;
• performs error correction processing to correct an error of each of the setting values stored in the memory;
• and
• performs a correction frequency change processing to change a correction frequency with which the error correction processing is performed in accordance with control processing that is performed by the processor, wherein
• the processor performs a first correction frequency change processing to decrease, when a frequency of correction by the error correction processing for a storage area that stores one of the setting values is changed to a high frequency, a frequency of correction by the error correction processing for one of the storage areas other than the storage area whose correction frequency is changed to a high frequency so as to be lower than the correction frequency of the storage area whose correction frequency is changed to a high frequency, and to increase, when a frequency of correction by the error correction processing for a storage area that stores one of the setting values is changed to a low frequency, a frequency of correction by the error correction processing for one of the storage areas other than the storage area whose correction frequency is changed to a low frequency so as to be higher than the correction frequency of the storage area whose correction frequency is changed to a low frequency.
