26.3.12.6 Graceful Stop Interrupt (GRA)
The graceful stopped interrupt (GRA) is asserted for the following conditions:
The GRA interrupt is triggered only once when the stopped state is entered. If the interrupt
is cleared while the stop condition persists, no further interrupt will be triggered.
26.3.13 IEEE 1588 Functions
26.3.13.1 Overview
To allow for IEEE 1588 or similar time synchronization protocol implementations, the
MAC is combined with a time-stamping module to support precise time stamping of
incoming and outgoing frames. 1588 Support is enabled when the register bit ENA_1588
is set to '1'.

pause received).
The assertion of GRS will not wait for an ongoing transaction on
the application side of the FIFO (FIFO read). If necessary, the
signal can be ANDed with the ff_rx_dval (considering proper
clock domains).
