Ok for transmit, but if you have to check a received TCP frame CRC,
you have to calculate it 'manually' ?!

User Manual is also online. In MAC2 register, set "CRC Enable" bit
to automatically add CRC before transmit. It's also called FCS
"Frame Check Sequence".

Hi,

I'm looking at the LPC23xx datasheet , but I'm not really sure if
there's an hardware way to calculate CRC for Ethernet RX/TX frame(like
the one on the microchip ENC28J60 controller even if it doesn't work :) ??

Kind regards.
