Quote from Reference Manual

Bits 7:6 PCF: Pass control frames

These bits control the forwarding of all control frames (including unicast and multicast

PAUSE frames). Note that the processing of PAUSE control frames depends only on RFCE

in Flow Control Register[2].

00: MAC prevents all control frames from reaching the application

01: MAC forwards all control frames to application except Pause control frames

10: MAC forwards all control frames to application even if they fail the address filter

11: MAC forwards control frames that pass the address filter.

00 or 01: MAC prevents all control frames from reaching the application

10: MAC forwards all control frames to application even if they fail the address filter

11: MAC forwards control frames that pass the address filter.

Looks like someone tried to fix manual and left old text.

So what is correct for PCF=01 ?
