M95P32 EEPROM driver: multiple EEPROM instances?

New question from M95P32 EEPROM - looking for a driver

@mƎALLEm Thank you for your advice. Although I need to adapt the code to my needs and lots of refactoring will be needed e.g. to use DMA and RTOS in async fashion, it got me started.
There is, however, one detail which puzzles me. PGEEZ1_M95P32_xxx functions accept Instance argument, which makes sense, but this argument is not used to set correct CTRL (CS) state. It seems like the code allows for multiple EEPROM instance but then does not handle multiple CS signal pins corresponding to those EEPROMs.
Am I missing something? See sample code fragment below.
