1.

Not tested in production. All table limits are guaranteed by design.

2.

CFG -11= 0 and CFG -12 = 0 (output tr = 30 ns; output tf = 20 ns); CFG-14=1 (no output gradual delay).

3.

If devices are connected in cascade and tclkr or tclkf is large, it may be critical to achieve the timing required for data

transfer between two cascaded devices.
