Filter logic [1:0]
Mode
TTX filter 2 enable
TTX filter 1 enable
Filter logic [1:0]: Allows 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 = Disabled (default)
1 = Enabled
TTX filter 1 enable: Provides for enabling the teletext filter function within the VDP.
0 = Disabled (default)
1 = Enabled
If the filter matches or if the filter mask is all 0s, then a true result is returned.
