of the PCI configuration space,
bits 7-0). Refer to the description
of DATA register for the meaning
of this field.
These bits are always read ac-
cessible. DATA7 is read only.
Cleared by H_RESET and is not
affected by S_RESET or setting
the STOP bit.
BCR45: OnNow Pattern Matching Register 1
Note:
This register is used to control and indirectly ac-
cess the Pattern Match RAM (PMR). When BCR45 is
written and the PMAT_MODE bit (bit 7) is 1, Pattern
Match logic is enabled. No bus accesses into PMR are
possible, and BCR46, BCR47, and all other bits in
BCR45 are ignored. When PMAT_MODE is set, a read
of BCR45, BCR46, or BCR47 returns all undefined bits
except for PMAT_MODE.
When BCR45 is written and the PMAT_MODE bit is 0,
the Pattern Match logic is disabled and accesses to the
PMR are possible. Bits 6-0 of BCR45 specify the ad-
dress of the PMR word to be accessed. Following the
write to BCR45, the PMR word may be read by reading
BCR45, BCR46 and BCR47 in any order. To write to
PMR word, the write to BCR45 must be followed by a
write to BCR46 and a write to BCR47 in that order to
complete the operation. The RAM will not actually be
written until the write to BCR47 is complete. The write
to BCR47 causes all 5 bytes (four bytes of BCR46-47
and the upper byte of the BCR45) to be written to what-
ever PMR word is addressed by bits 6:0 of BCR45.
Bit
Name
Description
31-16 RES
Reserved locations. Written as
zeros and read as undefined.

PMR_B0
Pattern Match RAM Byte 0. This
byte is written into or read from
Byte 0 of the Pattern Match RAM.
These bits are read and write ac-
cessible always. PMR_B0 is un-
defined after H_RESET, and is
unaffected by S_RESET and the
STOP bit.
7
PMAT_MODE
Pattern Match Mode. Writing a 1
to this bit will enable Pattern
Match Mode and should only be
done after the Pattern Match
RAM has been programmed.
These bits are read and write ac-
cessible always. PMAT_MODE is
reset to 0 after H_RESET, and is
unaffected by S_RESET and the
STOP bit.
6-0
PMR_ADDR
Pattern Match Ram Address.
These bits are the Pattern Match
Ram address to be written to or
read from.
These bits are read and write ac-
cessible always. PMR_ADDR is
reset to 0 after H_RESET, and is
unaffected by S_RESET and the
STOP bit.

This register is used to control and indirectly ac-
cess the Pattern Match RAM (PMR). When BCR45 is

BCR45 are ignored. When PMAT_MODE is set, a read
of BCR45, BCR46, or BCR47 returns all undefined bits
except for PMAT_MODE.
When BCR45 is written and the PMAT_MODE bit is 0,
the Pattern Match logic is disabled and accesses to the
PMR are possible. Bits 6-0 of BCR45 specify the ad-
dress of the PMR word to be accessed. Following the

BCR45, BCR46 and BCR47 in any order. To write to

PMR_B2
Pattern Match RAM Byte 2. This
byte is written into or read from
Byte 2 of the Pattern Match RAM.
These bits are read and write ac-

unaffected by S_RESET and the
STOP bit.

PMR_B1
Pattern Match RAM Byte 1. This

Byte 1 of Pattern Match RAM.
These bits are read and write ac-
