Hi Aju,

The TEST_PATTERN register (0x6c[16:13]) needs to be programmed to 5 for generating a ramp test pattern. This will be enabled by setting TEST_PATTERN_ENABLE (0x9D[14:14]) as 1.

Aju,

Yes, you're right TEST_PATTERN_ENABLE is 0xD9[14:14]. Sorry for the error. I couldn't understand what you're trying to ask here. If you're working in slave mode, you do need to give EXT_VD_IN pulses. I do not understand the problem.
