Positive power supply.
Ground supply.
During configuration, RESET forces the restart of configuration and a pull-up is
enabled. After configuration, RESET can be used as an FPGA logic direct input,
which causes all PLC latches/FFs to be asynchronously set/reset.
In the Master and asynchronous peripheral modes, CCLK is an output which strobes
configuration data in. In the slave or synchronous peripheral mode, CCLK
is input synchronous with the data on DIN or D[7:0]. In microprocessor and PCI
modes, CCLK is used internally and output for daisy-chain operation.
As an input, a low level on DONE delays FPGA start-up after configuration.*
As an active-high, open-drain output, a high level on this signal indicates that config-
uration is complete. DONE is also used in the embedded PCI core start-up
sequence. DONE has an optional pull-up resistor.
PRGM is an active-low input that forces the restart of configuration and resets the
boundary-scan circuitry. This pin always has an active pull-up.
This pin must be held high during device initialization until the INIT pin goes high.
This pin always has an active pull-up.
During configuration, RD_CFG is an active-low input that activates the TS_ALL
function and 3-states all of the I/O.
After configuration, RD_CFG can be selected (via a bit stream option) to activate the
TS_ALL function as described above, or, if readback is enabled via a bit stream
option, a high-to-low transition on RD_CFG will initiate readback of the configuration
data, including PFU output states, starting with frame address 0.
RD_DATA/TDO is a dual-function pin. If used for readback, RD_DATA provides con-
figuration data out. If used in boundary scan, TDO is test data out.

During powerup and initialization, M0—M2 are used to select the configuration
mode with their values latched on the rising edge of INIT; see Table 28 for the con-
figuration modes. During configuration, a pull-up is enabled.
After configuration, M2 can be a user-programmable I/O.*
During powerup and initialization, M3 is used to select the speed of the internal
oscillator during configuration with their values latched on the rising edge of INIT.
When M3 is low, the oscillator frequency is 10 MHz. When M3 is high, the oscillator
is 1.25 MHz. During configuration, a pull-up is enabled.
After configuration, M2 can be a user-programmable I/O pin.*

* The ORCASeries 3 FPGA data sheet contains more information on how to control these signals during start-up. The timing of DONE release
is controlled by one set of bit stream options, and the timing of the simultaneous release of all other configuration pins (and the activation of all
user I/Os) is controlled by a second set of options.
Pin Information
This section describes the pins and signals that perform FPGA-related functions. Any pins not described in Table 5
or here in Table 41 are user-programmable I/Os. During configuration, the user-programmable I/Os are 3-stated
and pulled-up with an internal resistor. If any FPGA function pin is not used (or not bonded to package pin), it is
also 3-stated and pulled-up after configuration.
