[Augustine_Yeh]

Hi Cypress

Could you help to confirm the following questions?

1.What is the purpose of EEPROM?
Does EEPROM save Boot code? We found it can upgrade firmware from datasheet, but we don't need this function.
Can we remove this EEPROM?

2.These pin are do not use (DNU). Can we let they be left floating?

 
3.Is SUSPEND pin defined as IO pin?
This pin is output pin on reference design. What is purpose that SUSPEND pin is defined as input pin?

Thanks!
