Three-state DATA output for configuration. Open-collector bi-directional pin for programming.
Clock input. Used to increment the internal address and bit counter for reading and
programming.
Input used to enable page download mode. When PAGE_EN is high the configuration download
address space is partitioned into 4 equal pages. This gives users the ability to easily store and
retrieve multiple configuration bitstreams from a single configuration device. This input works in
conjunction with the PAGESEL inputs. PAGE_EN must be remain low if paging is not desired.
When SER_EN is Low (ISP mode) this pin has no effect.
Notes:
1. This pin has an internal 20 KΩ pull-up resistor.
2. This pin has an internal 30 KΩ pull-down resistor.
