Channel [0—3] PPP Header Search. This register
will control the headers that channel [0—3] PPP
detach block looks for. Mismatched headers will be
noted in a separate counter (addresses 0x1118—
0x111F).
Controls the way the PPP headers are searched for
and passed through.

the protocol field remains.
(first 16 bits are 0xFF03; last 16 bits are defined by
fixed patterns and/or register values). A 32-bit match
is performed, and the 32 bits are all stripped. See

A value of 1 in this bit will enable a search for the
16-bit fixed value 0x8021.
A value of 1 in this bit will enable a search for the
16-bit fixed value 0x0021.
A value of 1 in this bit will enable a search of the
16-bit value in register address 0x10FB.
A value of 1 in this bit will enable a search of the
16-bit value in register address 0x10FA.
A value of 1 in this bit will enable a search of the
16-bit value in register address 0x10F9.
A value of 1 in this bit will enable a search of the
16-bit value in register address 0x10F8.
A value of 1 in this bit will enable a search of the
16-bit value in register address 0x10F7.
A value of 1 in this bit will enable a search of the

A value of 1 in this bit will enable a search of the
16-bit value in register address 0x10F5.
A value of 1 in this bit will enable a search of the
