ST7565The Common Output Status Select CircuitIn the ST7565 chips, the COM output scan direction can beselected by the common output status select command.(See Table 6.) Consequently, the constraints in IC layout atthe time of LCD module assembly can be minimized.StatusNormalReverseTable 6COM Scan Direction1/65 DUTY 1/49 DUTY 1/33 DUTY 1/55 DUTY 1/53 DUTYCOM0 → COM63COM63 → COM0COM0 → COM47COM47 → COM0COM0 → COM31COM31 → COM0COM0 → COM53COM53 → COM0COM0 → COM51COM51 → COM0Duty1/651/491/331/551/53ComCommon output pinsdir com[0:15] com[16:23] com[24:26] com[27:36] com[37:39] com[40:47] com[48:63] coms0 com[0:63] coms1 com[63:0] coms0 com[0:23] com[24:47] coms1 com[47:24] com[23:0] coms0 com[0:15] com[16:31] coms1 com[31:16] com[15:0] coms0 com[0:26] com[27:53] coms1 com[53:27] com[26:0] coms0 com[0:25] com[26:51] coms1 com[51:26] com[25:0] comsThe LCD Driver CircuitsThese are a 197-channel, that generate four voltage levelsfor driving the LCD . The combination of the display data, theCOM scan signal, and the FR signal produces the liquidcrystal drive voltage output.Figure 6 shows examples of the SEG and COM outputwave form.Ver 0.9 18/18 2001/01/11
