8.4.3 CROSS

CROSS pin will control the orientation of the integrated cross bar mux.

Upon de-assertion of RESETB followed by internally generated reset signal and 1ms delay, CROSS pin is sampled and latched.

The system needs to make sure that CROSS meets t_su_CROSS and t_hd_CROSS with respect to power supply ramp and RESETB de-assertion per Section 9.3.

Changes to the state of the CROSS input while RESETB is high will be ignored.
