DESCRIPTION
7
DO
test bit for forcing charge pump current down
0 = default value
1 = forcing down
6
UP
test bit for forcing charge pump current up
0 = default value
1 = forcing up
5
FTRILEVEL
denes the 3-level function mode
0 = automatic 3-level
1 = level selection with bit STRILEVEL
4
STRILEVEL
forces the state of 3-level function
0 = not 3-level mode
1 = 3-level mode
3
CKREFS
enables the PLL Ckref signal to be selected
0 = same as input
1 = input inverted
2
SOGSEL
enables the reference PLL between HSYNC input and SOG input to be selected
0 = HSYNC input
1 = SOG input
1 to 0
SOGI[1:0]
denes the SOG charge pump current; values are given in % of sync pulse/line length
00 = 14.8 % maximum (TV standards) and non-VESA standards
01 = 12.6 % maximum (all standards)
10 = 8.6 % maximum (HDTV standards) and non-VESA standards
11 = 0 test mode
