What does TFTv1 command 0x02 do?

[funnypolynomial]

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:

LCD Driving Wave Control (R02h)
D9=B/C
D8=EOR

B/C:
0 : Frame/Field inversion
1 : Line inversion
EOR:
EOR = 1 and B/C=1 to set the line inversion.

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