To enable flow control in Full-Duplex mode, set the
TXPAUS and RXPAUS bits in the MACON1 register.
Then, at any time that the receiver buffer is running out
of space, set the Flow Control Enable bits,
FCEN1:FCEN0 (EFLOCON<1:0>). The module will
automatically finish transmitting anything that was in
progress and then send a valid pause frame loaded
with the selected pause timer value. Depending on the
mode selected, the application may need to eventually
clear Flow Control mode by again writing to the FCEN
bits.

Bit 3
When the RXPAUS bit is set and a valid pause frame
arrives with a non-zero pause timer value, the module
will automatically inhibit transmissions. If the TXRTS bit
becomes set to send a packet, the hardware will simply
wait until the pause timer expires before attempting to
send the packet and subsequently, clearing the TXRTS
bit. Normally, this is transparent to the microcontroller,
and it will never know that a pause frame had been
received. Should it be desirable to know when the MAC
is paused or not, the user should set the PASSALL bit
(MACON1<1>), then manually interpret the pause
control frames which may arrive.
