Sensoray 614 Caption Overlay Bedienungsanleitung

Sensoray Model 614 Caption/Overlay Programming Guide I. Caption/Overlay Feature Summary • Up to 8 windows or fields • Up to 64 characters or bit

RAM Bitmap-Block #16~23, Data: 080 h – 0bf h RAM Bitmap-Block #24~31, Data: 0c0 h – 0ff h RAM Bitmap-Block #32~39, Data: 100 h – 13f

For Window-3 and Window-4: Each Bitmap-Block is composed of 16-bit/word x 8 words, which holds 8 pixels x 16 lines of one bitmap-block data or one

BbCh[5:0] is for choosing which bitmap-block or character font stored in the bitmap-block RAM: i.e. BbCh[5:0] = 0: choose Bitmap-block or Ch

Transp is for indicating if the caption/overlay is transparent: 0 – transparent, 1 – non transparent, with black background Y[2:0] is the color i
