Hi
I want to program UCD90120 chip to make the GPIO17 (Pin ID:24) to High. Can anybody suggest me the command sequence to do that?
Thanks in advance.

If you want to manually drive that GPIO, use GPIO_SELECT (0xFA) and GPIO_CONFIG (0xFB) commands:
Write Byte: Code = 0xFA, value = 0x18 (24d)
Write Byte: Code = 0xFB, value = 0x07
