For an NABTS system, the packet prefix consists of five bytes. Each byte contains four data bits (D[3:0]) interlaced
with four Hamming protection bits (H[3:0]):
Bit 7
Bit 6
Bit 5
Bit 4
Bit 3
Bit 2
Bit 1
Bit 0
D[3]
H[3]
D[2]
H[2]
D[1]
H[1]
D[0]
H[0]
Only the data portion D[3:0] from each byte is applied to a teletext filter function with the corresponding pattern bits
P[3:0] and mask bits M[3:0]. Hamming protection bits are ignored by the filter.
For a WST system (PAL or NTSC), the packet prefix consists of two bytes so that two patterns are used. Patterns
3, 4, and 5 are ignored.
The mask bits enable filtering using the corresponding bit in the pattern register. For example, a 1 in the LSB of mask 1
means that the filter module must compare the LSB of nibble 1 in the pattern register to the first data bit on the
transaction. If these match, then a true result is returned. A 0 in a bit of mask 1 means that the filter module must ignore
that data bit of the transaction. If all 0s are programmed in the mask bits, then the filter matches all patterns returning
a true result (default 00h).
Pattern and mask for each byte and filter are referred as <1,2><P,M><1,2,3,4,5> where:
<1,2> identifies the filter 1 or 2
<P,M> identifies the pattern or mask
<1,2,3,4,5> identifies the byte number
