CONTROL SIGNAL OUTPUT
Signal levels are LVCMOS/LVTTL compatible.
Serial Data Output / Test Data Output
Host Mode (JTAG/HOST = LOW)
SDOUT_TDO operates as the host interface serial output, SDOUT, used to
read status and configuration information from the internal registers of the
device.
JTAG Test Mode (JTAG/HOST = HIGH)
SDOUT_TDO operates as the JTAG test data output, TDO.
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Serial Data In / Test Data Input
Host Mode (JTAG/HOST = LOW)
SDIN_TDI operates as the host interface serial input, SDIN, used to write
address and configureation information to the internal registers of the
device.
JTAG Test Mode (JTAG/HOST = HIGH)
SDIN_TDI operates as the JTAG test data input, TDI.
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Serial Data Clock / Test Clock.
Host Mode (JTAG/HOST = LOW)
SCLK_TCK operates as the host interface burst clock, SCLK. Command
and data read/write words are clocked into the device synchronously with
this clock.
JTAG Test Mode (JTAG/HOST = HIGH)
SCLK_TCK operates as the JTAG test clock, TCK.
STATUS SIGNAL OUTPUT
Signal levels are LVCMOS/LVTTL compatible.
The DATA_ERROR signal will be LOW when an error within the received
data stream has been detected by the device. This pin is a logical 'OR'ing
of all detectable errors listed in the internal ERROR_STATUS register.
Once an error is detected, DATA_ERROR will remain LOW until the start of
the next video frame / field, or until the ERROR_STATUS register is read via
the host interface.
The DATA_ERROR signal will be HIGH when the received data stream has
been detected without error.
NOTE: It is possible to program which error conditions are monitored by
the device by setting appropriate bits of the ERROR_MASK register HIGH.
All error conditions are detected by default.
