Filter logic [1:0]:
Allow different logic to be applied when combining the decision of Filter 1 and Filter 2 as follows:
00 = NOR (default)
01 = NAND
10 = OR
11 = AND
Mode:
Indicates which teletext mode is in use:
0 = Teletext filter applies to 2 header bytes (default)
1 = Teletext filter applies to 5 header bytes
TTX filter 2 enable:
Provides for enabling the teletext filter function within the VDP.
0 = Disable (default)
1 = Enable
TTX filter 1 enable:
Provides for enabling the teletext filter function within the VDP.
0 = Disable (default)
1 = Enable
If the filter matches or if the filter mask is all zeros, then a true result is returned.
