My customer has something need to expliain.

In void Example_ProgramUsingAutoECC(void), including Fapi_issueProgrammingCommand and Fapi_doVerify,

Hi Anka,

Fapi_doVerify() reads 4-32-bit number for faster read operations. Writing 8 16-bits words also depends on flash controller architecture.

Hi Raieshway,

What is the specific difference between Fapi_doVerify() and Fapi_issueProgrammingCommand() in flash controller architecture?

The speed is difference: 4-32-bit and 8 16-bits?

Hi Anka,

You can use Fapi_doVerifyBy16bits() if you want to read 8 16-bit words. Speed wise it doesn't have much difference.
