// Line Byte/Word Count Register
//
// Bits 0-7 are in AUX[2], Bit 8 is in AUX[3].
//
// Because the Memory Interface is set to 16 bits, the
// Line Byte/Word Count Register counts in words.
// To calculate the Line Byte Count for different numbers of
// gray shades/colors, use the following formula:
//
//
//
//
//
switch (PanelGrayLevel)
WriteRegister(2, val & 0xff);
val2 = (val >> 8) & 0x01;
if (PanelD == PANEL_COLOR)
WriteRegister(3, val2);
//
// BytesPerScanLine is a global variable
//
switch (PanelGrayLevel)
