Internal vertical blanking pulse VBL when JMP = 0 and number of lines per field = constant
b) Description of VBL when JMP= 1
Start of VBL = VBS lines before the first complete line of the next field
(def. value 0)
if BSE = 0
end of VBL = end of line (VBE + 29) (odd field)
width of VBL = (VBS + VBE + 29) lines (odd field)(def. value 29)
if BSE = 1
end of VBL = end of line (RPP + VBE + 25) (odd field)
width of VBL = (VBS + RPP + VBE + 25) lines (odd field)
Note! If JMP = 1 the number of lines between the last ref. pulse and the end of
VBL is defined by VBE in the range of 7 (VBE = 0) to 14 (VBE = 7).
