Test Mode Select input, used to control the 1149.1 state machine.
Test Clock input pin, used to clock the 1149.1 state machine.
Test Data in pin, used to load data into device using 1149.1 state machine.
After power-up, this TAP port can be activated for configuration by sending
appropriate command. (Note: once a configuration port is selected it is
locked. Another configuration port cannot be selected until the power-up
sequence).
Output pin -Test Data out pin used to shift data out of device using 1149.1.
V
Mode pins used to specify configuration modes values latched on rising edge
of INITN. During configuration, a pull-up is enabled.
Open Drain pin - Indicates the FPGA is ready to be configured. During con-
figuration, a pull-up is enabled. If CFG1 and CFG0 are high (SDM) then this
pin is pulled low.
Initiates configuration sequence when asserted low. This pin always has an
active pull-up.
Open Drain pin - Indicates that the configuration sequence is complete, and
the startup sequence is in progress.
sysCONFIG chip select (Active low). During configuration, a pull-up is
enabled. After configuration it is user a programmable I/O pin.
sysCONFIG chip select (Active Low). During configuration, a pull-up is
enabled. After configuration it is user programmable I/O pin
Write Data on Parallel port (Active low). After configuration it is a user pro-
grammable I/O pin
sysCONFIG Port Data I/O. After configuration these are user programmable
I/O pins.
Output for serial configuration data (rising edge of CCLK) when using sys-
CONFIG port. After configuration, it is a user-programmable I/O pin.
Input for serial configuration data (clocked with CCLK) when using sysCON-
FIG port. During configuration, a pull-up is enabled. After configuration it is a
user-programmable I/O pin.
Sleep Mode pin - Active low sleep pin.þ When this pin is held high, the device
operates normally.þ When driven low, the device moves into Sleep Mode
after a specified time.This pin has a weak internal pull-up, but when not used
an external pull-up to V
Test Output Enable tri-states all I/O pins when driven low. This pin has a
weak internal pull-up, but when not used an external pull-up to V
mended.
