This card is equipped with a mask ROM in which the following typical PAD patterns have been already
written. PAD value is determined by selecting a desired PAD pattern, which can be done by key setting of
the SW 5 (elements 1, 2, 3) on this card, and programming of the PAD data by the ARTD command - PAD.
The selected PAD pattern and the programmed ARTD PAD data correspond as listed below.
