The following table describes the interrupt signals provided by the TEMAC core.
| Signal | Direction | Clock Domain | Description |
|---|---|---|---|
| mac_irq | Out | s_axi_aclk | Only available when the core is generated with AXI4-Lite Management Interface. This is the interrupt output from the interrupt controller. It is asserted when any of the interrupts, namely mdio_ready, interrupt_ptp_rx, interrupt_ptp_tx, or interrupt_ptp_timer has been enabled and set. See Interrupt Controller for more information. |
| interrupt_ptp_rx | Out | s_axi_aclk | Only available when the core is generated with AVB. This is asserted following the reception of any PTP packet by the RX PTP Packet Buffers. See RX PTP Packet Buffer for more information. |
| interrupt_ptp_tx | Out | s_axi_aclk | Only available when the core is generated with AVB. This is asserted following the transmission of any PTP packet from the TX PTP Packet Buffers. See TX PTP Packet Buffer for more information. |
| interrupt_ptp_timer | Out | s_axi_aclk | Only available when the core is generated with AVB. This interrupt asserts every 1/128 seconds as measured by the RTC. This acts as a timer for the PTP software algorithms. See Real-Time Clock for more information. |
