S1D13503
X18A-G-003-05
The S1D13503 latches the state of the SRAM data bus during RESET to determine the power-on configuration. The chip
has internal pull-down resistors and therefore external pull-ups are only necessary when requiring a ’1’ state, see below.

Where 1 = pull-up with a 10K resistor; 0 = no pull-up resistor
All register settings are completely programmable and are dependent on display type, resolution, color and mode of
operation, see Functional Specification for details.
