CC
(1)
Open collector reset state indicator. Driven Low during power-up reset, released when power-up
is complete. (recommended 4.7 kΩ pull-up on this pin if used).
The serial enable input must remain High during FPGA configuration operations. Bringing
SER_EN Low enables the 2-Wire Serial Programming Mode. For non-ISP applications,
SER_EN should be tied to V
+3.3V (±10%).
Notes:
1. This pin has an internal 20 kΩ pull-up resistor.
