The Calculations for HClksTotal are
HClksTotal = Number of Horizontal Clocks - 1
= 20 -1
= 19
The Calculations for HSyncStart are
HSyncStart = HClksTotal + Offset of Sync
= 19 + 0
= 19
TheCalculations for HSyncStop are
HSyncStop = HClksTotal - Screen Width + Offset of Sync
= 19 - 16 + 0
= 3
TheCalculations for HActiveStrt are
HActiveStrt = HClksTotal + Offset of HActive
= 19 -1
= 18
The Calculations for HActiveStop are
HActiveStop = HClksTotal - Screen Width + Offset of HActive
= 19 - 16 -1
= 2
The Calculations for HBlankStrt are
HBlankStrt = HClksTotal + Offset of HActive
= 19 -1
= 18
The Calculations for HBlankStop are
HBlankStop = HClksTotal - Screen Width + Offset of HActive
= 19 - 16 -1
= 2
