What does TFTv1 command 0x02 do?

I’m using TFT_Touch_Shield_V1 from GitHub.
I note that

void TFT::init (void)
has

... sendCommand(0x0002); sendData(0x0700); ...
But there is no command 02h listed in Table 9 “System Function Command List” in ST7781R_datasheet.pdf.
Can anyone shed some light on what TFT command 02h does? I’ve googled without success. Just curious!

thanks

In the ILI9325 data sheet (which seems to implement the same feature-set) I found:

So 0x700 is “setting line inversion”. Curiosity satisfied, but not a whole lot wiser :smiley:
