Hello,
I'm working on the Intel 82579LM linked to a QM77 PCH (7/C210 Series Chipset).
When activating the Tx functionalities, using the TCLT register ( p193 of Intel® 82579 GbE PHY: Datasheet, Vol. 2.1 )
I noticed that if the "Reserved" "Read only" bit 28 was not specifically set to value '0b1', the Tx functionalities do not work.
Although I agree it is not "best-practice" to set "Reserved" bits, is this behavior normal ?
Many thanks !
