Shifting the LOD Data Out
SOUT outputs the LOD data as shown in Figure 14, where:
• XLAT rising edge
Holds the LOD status flag. SOUT outputs LOD OUT15 data. BLANK must be low.
• XLAT = H
Sets or resets the input shift register depending on each LOD data.
Set/Reset function is higher priority than shifting the register value. If XLAT is high and the SCLK pin is
pulsed, all LOD data are kept in the shift register and SOUT keeps the LOD OUT15 data.
• XLAT = L
Ready to shift out LOD data by SCLK. SOUT contains LOD OUT15 data at this time. BLANK can be high or
low during this time.
• SCLK rising edge
SOUT outputs LOD OUT14 at the first SCLK rising edge. SOUT outputs LOD OUT13 at the second SCLK
rising edge, and continues to output the next LOD data at each SCLK rising edge.
