6.3.5 XTI,XTO and CLK_OUT timings

txto = 1.40 + pad_timing (Cload_XTO) ns

tclk_out = 4 + pad_timing (Cload_CLK_OUT) ns

Note: In "multimedia" mode, the CLK_OUT pad is DATA_REQ. In that case, no timing is given between the XTI input and this pad.

6.3.6 RESET

The Reset min duration (t_reset_low_min) is 100ns
