K22FN256 - Writing to External EEPROM

Hi, as you see above I'm using the K22FN256 uC and attached to pins 49 - 52 (SPI) is an EEPROM chip (Adesto Technologies, Digikey Part Number: 1265-1147-1-ND ).   I'm not clear how to get started writing to EEPROM.

I understand the CS', followed by SCK, followed by SO or SI is important.

 

I also understand there's OPCodes that are used to Read/Write and/or Erase the EEPROM.  

I'm not sure how to setup a function that can carry this out.  Can someone offer any suggestions?

 

Thanks,

 

Brian
