In the EMAC User Guide (sprufl5a), Section 3.2 (EMAC Control Module) describes a SOFTRESET register (EMAC Control Module Software Reset Register). When I write a 1 to this register, I never read back a 0, so the soft reset is never completed. Can you point me to a cause for this and how to determine what the cause is?

Has the EMAC been enabled in the PSC?

Also, in section 5 (EMAC Module Registers), section 5.34 describes a register with the same name (SOFTRESET). What is the difference??

The "EMAC Control Module" and the "EMAC Module" are separate logical blocks as shown in this figure from the user guide:

Each block has its own corresponding SOFTRESET bit.

So the softreset is unique to each module then?
