Operating Mode Selection

This LSI supports only operating mode 7, that is, the advanced single-chip mode. The operating
mode is determined by the setting of the mode pins (MD2 to MD0). Only mode 7 can be used in
this LSI. Therefore, all mode pins must be fixed high, as shown in table 3.1. Do not change the
mode pin settings during operation.
