1588 Port 2 RX Interrupt (1588_PORT2_RX_INT)
This interrupt indicates that a packet received by Port 2 matches the
configured PTP packet and the 1588 clock was captured.
1588 Port 2 TX Interrupt (1588_PORT2_TX_INT)
This interrupt indicates that a packet transmitted by Port 2 matches the
configured PTP packet and the 1588 clock was captured.
1588 Port 1 RX Interrupt (1588_PORT1_RX_INT)
This interrupt indicates that a packet received by Port 1 matches the
configured PTP packet and the 1588 clock was captured.
1588 Port 1 TX Interrupt (1588_PORT1_TX_INT)
This interrupt indicates that a packet transmitted by Port 1 matches the
configured PTP packet and the 1588 clock was captured.
1588 Port 0(Host MAC) RX Interrupt (1588_MII_RX_INT)
This interrupt indicates that a packet from the switch fabric to the Host MAC
the matches the configured PTP packet and the 1588 clock was captured.
Note:
1588 Interrupt Status and Enable Register (1588_INT_STS_EN)
This read/write register contains the IEEE 1588 interrupt status and enable bits.
Writing a 1 to any of the interrupt status bits acknowledges and clears the interrupt. If enabled, these
interrupt bits are cascaded into bit 29 (1588_EVNT) of the
a 1 to any of the interrupt enable bits will enable the corresponding interrupt as a source. Status bits
will still reflect the status of the interrupt source regardless of whether the source is enabled as an
interrupt in this register. Bit 29 (1588_EVNT_EN) of the
be set in order for an actual system level interrupt to occur. Refer to
on page 49
For Port 0, receive is defined as data from the switch fabric, while
transmit is to the switch fabric.
