Pin Type
Serial data output. The DATA pin connects to the
DATA0 of the FPGA. DATA is latched into the FPGA
on the rising edge of DCLK.
The DATA pin is tri-stated before configuration and
when the nCS pin is high. After configuration, the
EPC2 device will drive DATA high, while the EPC1
and EPC1441 device will tri-state DATA.
Clock output when configuring with a single
configuration device or when the configuration
device is the first (master) device in a chain. Clock
input for the next (slave) configuration devices in a
chain. The DCLK pin connects to the DCLK of the
FPGA.
Rising edges on DCLK increment the internal
address counter and present the next bit of data on
the DATA pin. The counter is incremented only if the
OE input is held high, the nCS input is held low, and
all configuration data has not been transferred to the
target device.
After configuration or when OE is low, the EPC1,
EPC2 and EPC1441 device will drive DCLK low.
Output enable (active high) and reset (active low).
The OE pin connects to the nSTATUS of the FPGA.
A low logic level resets the address counter. A high
logic level enables DATA and the address counter to
count. If this pin is low (reset) during configuration,
the internal oscillator becomes inactive and DCLK
drives low. Refer to
page
The OE pin has an internal programmable 1-k
resistor in EPC2 devices. If internal pull-up resistors
are use, external pull-up resistors should not be used
on these pins. The internal pull-up resistors can be
disabled through the Disable nCS and OE pull-ups
on configuration device option.
