5. Pin Description
Three-state DATA output for FPGA configuration. Open-collector bi-directional pin for configura-
tion programming.
Three-state clock. Functions as an input when the Configurator is in programming mode (i.e.
SER_EN is Low) and as an output during FPGA configuration.
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.
