ELECTRICAL CHARACTERISTICS
TIMING DIAGRAMS
Figure 5. Serial Interface Timing Diagrams
Twelve bits immediately before start-up of STRB are
always effective. Upon power on, the internal power on reset
works to initialize the registers. Serial data is fetched in the
order of Add_[3], Add_[2], ..., Add_[0], DATA1_[3],
DATA1_[2], ...., DATA2_[0].
