3.8.4. Reset Signals—Descriptions
Name | Width | Domain | Direction | Type | Description |
---|---|---|---|---|---|
tx_reset | 1 | Asynchronous | Input | N/A | TX reset input for TX PMAs and TX datapath. Must be kept asserted until tx_reset_ack is asserted. Applies to all TX channels in a F-Tile PMA/FEC Direct PHY Intel® FPGA IP instance. |
tx_reset_ack | 1 | Asynchronous | Output | N/A | TX fully in reset indicator. |
rx_reset | 1 | Asynchronous | Input | N/A | RX reset input for RX PMAs and RX datapath. Must be kept asserted until rx_reset_ack is asserted. Applies to all RX channels in a F-Tile PMA/FEC Direct PHY Intel® FPGA IP instance. |
rx_reset_ack | 1 | Asynchronous | Output | N/A | RX fully in reset indicator. |
reconfig_pdp_reset | 1 | Asynchronous | Input | Datapath Avalon® Memory Mapped Interface | Reconfiguration Interface Reset |
reconfig_xcvr_reset | 1 | Asynchronous | Input | PMA Avalon® Memory Mapped Interface | Active-high synchronous reset. Assert this signal to reset the PMA reconfiguration interface. |
tx_ready | 1 | Asynchronous | Output | N/A | Status port to indicate when TX PMAs and TX datapath are reset successfully and ready for data transfer. |
rx_ready | 1 | Asynchronous | Output | N/A | Status port to indicate when RX PMAs and RX datapath are reset successfully and ready for data transfer. |
tx_am_gen_start | 1 | Asynchronous | Output | N/A | When using FEC, indicates when to start sending alignment markers. This clears after tx_am_gen_2x_ack is asserted. |
tx_am_gen_2x_ack | 1 | Asynchronous | Input | N/A | When using FEC, you must indicate to the reset sequencer at least 2 alignment markers were sent since tx_am_gen_start is asserted. This signal should be deasserted after tx_am_gen_start is deasserted. |
