The Calculations for HClkStrt are
HClkStrt = HClkstotal - Offset of HClk
= 19 - 6
= 13
The Calculations for HClkStop are
HClkStop = HClksTotal - Screen Width + Offset of HClk
= 19 - 16 - 6
= -3
Since -3 is not in the range of 0 and HClksTotal, add the number of Horizontal Clocks.
= -3 + Number of Horizontal Clocks
= -3 + 20
HClkStop = 17
The values for HSyncStart, HSyncStop, HActiveStrt, HActiveStop, HBlankStrt, HBlankStop, HClkStrt and
HClkStop are shown in Figure 2.
