Master SelectMAP Mode
This mode is a master version of the SelectMAP mode. The
device is configured byte-wide on a CCLK supplied by the
Virtex-II Pro FPGA device. Timing is similar to the Slave
SerialMAP mode except that CCLK is supplied by the
Virtex-II Pro FPGA.
Boundary-Scan (JTAG, IEEE 1532) Mode
In Boundary-Scan mode, dedicated pins are used for con-
figuring the Virtex-II Pro device. The configuration is done
entirely through the IEEE 1149.1 Test Access Port (TAP).

Configuration Sequence
The configuration of Virtex-II Pro devices is a three-phase
process. First, the configuration memory is cleared. Next,
configuration data is loaded into the memory, and finally, the
logic is activated by a start-up process.

Virtex-II Pro device configuration using Boundary-Scan is
compatible with with IEEE 1149.1-1993 standard and the
new IEEE 1532 standard for In-System Configurable (ISC)
devices. The IEEE 1532 standard is backward compliant
with the IEEE 1149.1-1993 TAP and state machine. The
IEEE Standard 1532 for In-System Configurable (ISC)
devices is intended to be programmed, reprogrammed, or
tested on the board via a physical and logical protocol. Con-
figuration through the Boundary-Scan port is always avail-
able, independent of the mode selection. Selecting the
Boundary-Scan mode simply turns off the other modes.
Configuration is automatically initiated on power-up unless
it is delayed by the user. The INIT_B pin can be held Low
using an open-drain driver. An open-drain is required since
INIT_B is a bidirectional open-drain pin that is held Low by a
Virtex-II Pro FPGA device while the configuration memory
is being cleared. Extending the time that the pin is Low
causes the configuration sequencer to wait. Thus, configu-
ration is delayed by preventing entry into the phase where
data is loaded.
The configuration process can also be initiated by asserting
the PROG_B pin. The end of the memory-clearing phase is
signaled by the INIT_B pin going High, and the completion
of the entire process is signaled by the DONE pin going
High. The Global Set/Reset (GSR) signal is pulsed after the
last frame of configuration data is written but before the
start-up sequence. The GSR signal resets all flip-flops on
the device.
The default start-up sequence is that one CCLK cycle after
DONE goes High, the global 3-state signal (GTS) is
released. This permits device outputs to turn on as neces-
sary. One CCLK cycle later, the Global Write Enable (GWE)
signal is released. This permits the internal storage ele-
ments to begin changing state in response to the logic and
the user clock.
The relative timing of these events can be changed via con-
figuration options in software. In addition, the GTS and
GWE events can be made dependent on the DONE pins of
multiple devices all going High, forcing the devices to start
