asserting the ENASER signals at different times. ENAOCT must remain asserted while any
calibration is ongoing. You must set nCLRUSR low for one OCTUSRCLK cycle before each
ENASER[N] signal is asserted. In
time to initialize OCT calibration block 0, this does not affect OCT calibration block 1,
whose calibration is already in progress.

If only R
signal only requires to be asserted for 240 OCTUSRCLK cycles.
You must assert the ENASER signal for 28 OCTUSRCLK cycles for serial transfer.
The following sections describe the different termination schemes for the I/O
standards used in Stratix IV devices.
Voltage-referenced I/O standards require both an input reference voltage, V
termination voltage, V
termination voltage of the transmitting device.
