| #### SDRAM DQM lines and CE are hardwired to ground, CKE is hardwired to VCC | |
| #### PHY Clock is 125MHz, on the PHY0 and PHY1 RXCLK inputs | |
| #### 25MHz Clock on CLK25 | |
| #### MDIO and RESET is shared between both PHYs | |
| #### FLASH Clock, if needed in user logic, needs to be enabled trough USRMCLK | |
| #### The INPUT_KEY_RC Pin is filtered with a RC combination | |
| #### The GPIO Connectors are named after their pins on the connector. |

| I injected 5V on C60 (Fat ceramic cap , on top lower right corner near the sodimm edge) | |
| The Module needs a fair ammount of current to start up properly. I had my lab supply at 3A current | |
| limit, with the original config bitstream off the config prom on the module it draws about 700mA after startup |
