| Pin Name | Mode | Function | Default Configuration |
|---|---|---|---|
| RESIN | Input | Reset input | Active low reset input, default mapping forces POR_B reset to Zynq PS. |
| PGOOD | Output | Power good | Active high when all on-module power supplies are working properly. |
| MODE | Input | Boot mode | Force low for boot from the SD card. Latched at power-on only, not during soft reset! |
| EN1 | Input | Power enable | High enables the DC-DC converters and on-board supplies. Not used if NOSEQ is high. |
| NOSEQ | Input | Power sequencing | Forces the 1.0V and 1.8V DC-DC converters always ON when high. |
| JTAGMODE | Input | JTAG select | Keep low for FPGA JTAG access. |
