C0 : C0 = 0 : mixed mode
C0 = 1 : full page mode
C1 : C1 = 0 : the character background is controlled by BE (see character word description)
C1 = 1 : all displayed character backgrounds are disabled
C2 : C2 = 0 : display off
C2 = 1 : display on
C3 : C3 = 0 : the characters are colored according to the character attribute and the color register
values (i.e. CBACKG and CBORD)
C3 = 1 : the character foreground, border and background colors are all set to the character
attribute value (see paragraph 1.2). This option is mainly intended for full page mode,
CVBS or Y/C output
C4 : C4 = 0 : 1.0 second blinking period
C4 = 1 : 0.5 second blinking period
C[6:5] : C[6:5] = 00 : blinking off
01 : 0.75 blinking duty cycle
10 : 0.5 blinking duty cycle
11 : 0.25 blinking duty cycle
C7 : C7 = 0 an external input composite sync is taken from the CSYNC pin
C7 = 1 the sync is extracted by the STV5730.The currently active sync is output on the
CSYNC pin
C8 : C8 = 0 : the standard is NTSC, 60Hz
C8 = 1 : the standard is PAL or SECAM with M6 = 0, 50Hz
C9 : C9 = 0 : character color encoding is disabled
C9 = 1 : character color encoding is enabled
C10 : C10 = 0 : the luminance levels are generated internally
C10 = 1 : the luminance levels are provided by the LESCREEN and LECHAR input pins.
C11 : C11 = 0 : Video Full Page Mode. A stable full page mode text is displayed while the screen
background is the unlocked video input signal.
C11 = 1 : Normal full page mode is active.
The output of this register is synchronized by the horizontal sync (except C7). The RESET message clears
this register.
