HP11 to HP0 = (0000000000002) and (0000001001112) setting is forbidden. The vertical start location is specified using the 11 bits from VP10 to VP0. VP10 to VP0 = (000000000002) setting is forbidden. If HS is the horizontal display start location, HS = T ✕ ( 2 HPn + m) T: Period of display frequency 4055 settings are possible. m : offset value differ for the setting of the register EXCK0 and EXCK1. It shown below. 11 Σ n = 0 If VS is the vertical display start location, VS = H ✕ 2 VPn H : Cycle with the horizonal synchronizing pulse 2047 settings are possible. HS*(shown left) shows horizontal display start location this is register B/F (address 12716) = "0" is set. n n 10 Σ n = 0 EXCK1 EXCK0 m 0 0 13 0 1 13 1 0 Do not set 1 1 19 Fix to "0". Can not be used. DA Function Remarks Register Contents Status (3) Address 12216 Note 1: The mark around the status value means the reset status by the "L" level is input to AC pin. 2: Set up the horizontal and vertical display start location so that display range may not exceed it. Set the character code "1FF16" (blank without background) for the display RAM of the part which the display range exceeds. |
