MSP430F2410: I2C stretching

Fabio Fontana

Part Number: MSP430F2410

Hi,

for our application we use the microcontroller I2C port to communicate with a SFP+, scope is to make some stress tests of this interface,

is it possible modify the I2C timing parameters in order to verify if the SFP+ meets the standars, in term of example set-up and hold time?

if this microcontroller doesn't support this function, is there any other p/n to meet this?

Thanks.

    Hello Fabio,

    You will not be able to sample and holding time of individual bits or other spec aspects of TX/RX bits, but if you want to just test clock stretching you should be able to do this. To introduce clock stretching, you would need to delay filling the TXBuff is transmitting or delay reading the RXbuff if receiving.
