Pin Description
5.1
DATA(1)
Three-state DATA output for FPGA configuration. Open-collector bi-directional pin for configura-
tion programming.
5.2
DCLK(1)
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.
5.3
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 k
pull-up resistor.
2. This pin has an internal 30 k
pull-down resistor.
