After display refresh command, BUSY_N signal will become “0”. (12) Data start transmission 2 (DTM2) (R13H) Action W/R C/D D7 D6 D5 D4 D3 D2 D1 D0 Starting data transmission 0 0 0 0 0 1 0 0 1 1 0 1 Pixel1 Pixel2 Pixel3 Pixel4 Pixel5 Pixel6 Pixel7 Pixel8 0 1 .. .. .. .. .. .. .. .. 0 1 Pixel (n-7) Pixel (n-6) Pixel (n-5) Pixel (n-4) Pixel (n-3) Pixel (n-2) Pixel (n-1) Pixel (n) The command define as follows: The register is indicates that user start to transmit data, then write to SRAM. While data transmission complete, user must send command 11H. Then chip will start to send data/VCOM for panel. In B/W mode, this command writes “NEW” data to SRAM. In B/W/Red mode, this command writes “RED” data to SRAM. (13) Auto Sequence (AUTO) (R17H) Action W/R C/D D7 D6 D5 D4 D3 D2 D1 D0 Auto Sequence 0 0 0 0 0 1 0 1 1 1 0 1 Code[7:0] The command can enable the internal sequence to execute several commands continuously. The successive execution can minimize idle time to avoid unnecessary power consumption and reduce the complexity of host’s control procedure. The sequence contains several operations, including PON, DRF, POF, DSLP. AUTO (0x17) + Code(0xA5) = (PON → DRF → POF) AUTO (0x17) + Code(0xA7) = (PON → DRF → POF → DSLP) (14) BIST mode (BIST) (R18H) Action W/R C/D D7 D6 D5 D4 D3 D2 D1 D0 BIST 0 0 0 0 0 1 0 1 1 1 0 1 1 0 1 0 0 1 0 1 0 1 1 0 1 0 0 1 0 1 GDEW0154M09 www.e-paper-display.com 31/58 1.54 inch Series |
