Interface
The display module is equipped with a DCT4 compatible LCD controller (Driver) with bi-direc-

chip. The maximum clock frequency of the OMAP1510 µWire is 3.0 MHz. GPIO12 is the reset
signal for the CMT display.
Because of different logic levels of OMAP (2,8 V) and display (1,8 V), level shifters are used in
the following signal lines: SDA, CSX, RESX and SCL.
