U8g2: Help mapping digital lines for JLX256128

[morosanl]

Hi, I got this LCD screen "JLX256128G-256, 5V parallel input" and I'm having trouble identifying digital lines. From their datasheet:

8 A0(RS) Register selection signal H: data register 0: instruction register (written as "CD" on the IC data)
9 RST Reset Low level reset, after the reset is completed, return to high level, the LCD module starts to work
10 CS Chip Select Low level chip select
19 RD(E) Enable signal 6800 timing: enable signal
20 WR Read/write 6800 Timing: H: Read data L: write data
and here is the constructor:
U8G2_ST75256_JLX256128_1_6800 u8g2(U8G2_R0, d0, d1, d2, d3, d4, d5, d6, d7, en, cs, dc, rst);
So far I've identified :
RD(E) -> en,
CS -> cs,
??? - > dc
RST -> rst
Which one goes to dc? Am I correct with the other ones?

DC=RS
