OCT Calibration Block Modes of Operation

For example,
voltage. If a group of I/O banks has the same V
calibration block to calibrate the group of I/O banks placed around the periphery.
Because 3B, 4C, 6C, and 7B have the same V
I/O banks (3B, 4C, 6C, and 7B) with the OCT calibration block (CB7) located in bank
7A. You can enable this by serially shifting out OCT R
OCT calibration block located in bank 7A to the I/O banks located around the
periphery.
I/O banks that do not contain calibration blocks share calibration blocks with I/O
banks that do contain calibration blocks.

Power-Up Mode
In power-up mode, OCT calibration is automatically performed at power up.
Calibration codes are shifted to selected I/O buffers before transitioning to user
mode.
