The addresses of the lter match and mask patterns are from 0xFFE00
to 0xFFF7F. The address location for match/mask pattern set M, byte N,
is:
pattern[set M, byte N] address =
0b1111.1111.111n.nnnm.mmmm
where M = 0bmmmmm is {0-31}, and N = 0bnnnn is {0-11}
Each address location contains one byte of match pattern and one byte
of mask pattern.
MATCH REGISTER
Match Register set m, byte n
[15:8]
This is byte n of the 12-byte matching pattern.
MASK REGISTER
Mask Register set m, byte n
[7:0]
This is byte n of the 12-byte matching pattern. Each bit
of the masking pattern controls the ltering of each bit of
the section data. When a masking bit is set to 0, ltering
is active for that corresponding bit. When the masking bit
is set to 1, the corresponding bit pattern is a “don’t care”
bit.
information on the use of the match and mask patterns.

(Group 3)
This group of registers controls the processing of transport adaptation

eld from all other PIDs can be stored in this cyclic buffer, provided their
AF bit is set to 1.
