Time Delay

The S5U13705B00C evaluation board is designed to use the GPIO0 signal to control the LCD bias power. The following settings allow configuration of the necessary delays.

Hardware Power Save Enable

When this box is checked, Hardware Power Save using

 

GPIO0 is enabled. When this box is unchecked, the

 

Hardware Power Save function is not available.

Power Down Time Delay

This setting controls the time delay between when the

 

LCD panel is powered-off and when the S1D13705

 

control signals are turned off. This setting must be

 

configured according to the specification for the panel

 

being used.

 

This value is only used by Epson evaluation software

 

designed for the S5U13705B00C evaluation board.
