User Mode
In user mode, the OCTUSRCLK, ENAOCT, nCLRUSR, and ENASER[9..0] signals are used to
calibrate and serially transfer calibration codes from each OCT calibration block to
any I/O.

blocks are in calibration mode; when ENAOCT is 0, all OCT calibration blocks are in
serial data transfer mode. The OCTUSRCLK clock frequency must be 20 MHz or less.
You must generate all user signals on the rising edge of OCTUSRCLK.

Enable OCT Termination (Generated by user IP).
When ENOCT = 0, each signal enables the OCT serializer for the
corresponding OCT calibration block.
When ENAOCT = 1, each signal enables OCT calibration for the
corresponding OCT calibration block.
Serial-to-parallel load enable per I/O bank.
