Hi @all

For Backgound Nowhow ist this Question : as Example :
Transfer Modus ist UDP, and the PC sends a packet to the EasyTCP. The
EasyTCP is a Interrupt (T0) make. But the IRQ is desable, on this time i write a Block on the EEprom (during 1 Second).

After the Block is writing, standing the IRO allways On the MCU and the ISR is working ? ( maybe is a Edge trigger ?)

and futher : the Packet is recived, but the MCU has not Time to work the ISR (even now the EEpron is writing for a second). And in the time for writing the EEprom a next Packet was sending from the PC. What now ? Ist the first packet los or was the next Packet not recived, or was two Packet in the Buffer and the MCU will read first the frist Packet and then the last Packet ? Question over Question how now the Answer
