Timing Options for t₄₅
The wiring shown in the Figure 3-22 provides three useful timing options for t₄₅. depending on the signals selected
with the alternate output lines (ALT1 to ALT7) in the ports:
• EN01 - FCLN, SON, EN0, EN1
- t₄₅ reference timing
• EN01D - FCLND, SOND, EN0, EN1 - t₄₅ window shifted to the left
• EN23 - FCLN, SON, EN2, EN3
- t₄₅ window shifted to the right
The timings corresponding to EN01, EN01D, and EN23 are defined in the LVDS mode. In order to use the EN23
timings, the application should use the EN2 and EN3 outputs of the MSC module.

Mapping B, CMOS MP Pads
This timing applies for the dedicated CMOS pads, pin Mapping B:
• MP strong sharp (MPss) output pads for the clock and the data signals
• MP strong sharp or strong medium (MP+ss or MP+sm) output pads for enable signals
