RES[1:0]: Display Resolution setting (source x gate)
00b: 400x300 (Default) Active source channels: S0 ~ S399. Active gate channels: G0 ~ G299.
01b: 320x300 Active source channels: S0 ~ S319. Active gate channels: G0 ~ G299.
10b: 320x240 Active source channels: S0 ~ S319. Active gate channels: G0 ~ G239.
11b: 200x300 Active source channels: S0 ~ S199. Active gate channels: G0 ~ G299.
REG_EN: LUT selection
0: LUT from OTP. (Default)
1: LUT from register.
BWR: Black / White / Red
0: Pixel with B/W/Red. (Default)
1: Pixel with B/W.
UD: Gate Scan Direction
0: Scan down. First line to last line: Gn-1 → Gn-2 → Gn-3 → … → G0
1: Scan up. (default) First line to last line: G0 → G1 → G2 → … → Gn-1
SHL: Source Shift direction
0: Shift left First data to last data: Sn-1 → Sn-2 → Sn-3 → … → S0
1: Shift right. (default) First data to last data: S0 → S1 → S2 → … → Sn-1
SHD_N: Booster Switch
0: Booster OFF, register data are kept, and SEG/BG/VCOM are kept 0V or floating.
1: Booster ON (Default)
When SHD_N become LOW, charge pump will be turned OFF, register and SRAM data will keep until VDD OFF, and
SD output and VCOM will remain previous condition. SHD_N may have two conditions: 0v or floating.
RST_N: Soft Reset
1: No effect (Default). Booster OFF, Register data are set to their default values, and SEG/BG/VCOM: 0V
When RST_N become LOW, the driver will be reset, all registers will be reset to their default value. All driver
functions will be disabled. SD output and VCOM will base on previous condition. It may have two conditions: 0v or
floating.
