10. Conditions on Overwriting MIXED DECAY TIMING Table
11. Data Input Signal at Setting Mixed Decay Timing Table
If the following conditions are satisfied, the table can be overwritten.
When power is first turned on, the initial values in the table above are set as defaults.
Once latched, data are not cleared except by VDDR (power-on and power-off reset).
Next, after the mode changes to SETUP, the data are retained until mixed decay timing data are input and
latched.
• When RESET = H (when RESET = L, the shift register is cleared, thus data cannot be input)
• When an internal reset is not triggered.
Data No.
