Example Connection in Single-chip Mode (when Using
User Power)
In a user system, from TAUX3 and TMODE of AF220/AF210/AF120/AF110, "1" for MD1
and "0" for MD0 are input to the MD2 and MD0 mode pins, which have been set to the
single chip mode; this changes the mode to serial write mode. (Serial write mode:MD2,
MD1, and MD0=110)
