Reference:TI-opt9221.pdf 39~40page
Working conditions:
1. Opt9221 is set to Master serial configuration mode.
2.TIC_CONFIGZ pin pulled high,TIC_CEz pin pulled high low。SPI communication waveform exists between OPT9221 and eeprom。pin is still at the bottom of the potential
1.As shown in the figure below,Opt9221 reads the TFC configuration to eeprom,But TIC_CONF_DONE pin remains low potential,INT_OUT pin remains high potential。
OPT9221 is always in the configuration T CONF phase, Never complete configuration。
1.How to verify that the communication between EEPROM and opt9221 is correct?
2.Do <.tie>files need to be imported to EEPROM for opt9221 to work properly?
3.If I need to import a <.tie>file,How to import?
