a) The effective range for Vertical Blanking Time:
b) The "default value if disabled" for Vertical Blanking Time:
c) The effective range for Start Vertical Scan:
d) The effective range for Vertical Scan (total width: 10 Bit): 160 ... 684 lines.
e) The "default value if disabled" for Vertical Scan equals the number of lines of the
source signal reduced by the control value for Start Vertical Scan. (E.g.: input signal:
262 lines per field; Start vertical scan = 8 lines; then (if SSE = 1, STE = 0) vertical
scan = 262 - 8 = 254 lines.
At power on the RAM containing the control items is cleared. Therefore all data are zero
by default before transferring individual values via
Allowed values out of the effective range are limited, e. g. Vertical blanking time = 3 is
limited to 16 if STE = 0 (that means a minimum of 16 lines is blanked).
There are five bits (SRSE, BSE, SSE, STE, GBE) in the deflection control byte 1 for
disabling some control items. If one of these bits is "0", the value of the corresponding
control item will be ignored and replaced by the value "default value if disabled" in the
table above.
