MCLP:
The CLP bit contains the mask pattern for the eighth bit of the fourth octet of the 53-octet cell.
This mask is applied to this register to select the bits included in the cell filter. Logic 1 in this
bit position enables the CLP bit in the pattern register to be compared. Logic 0 causes the
masking of the CLP bit. The default enables the register bit comparison.
MPTI[3:0]:
The MPTI[3:0] bits contain the mask pattern for the fifth, sixth, and seventh bits of the fourth
octet of the 53-octet cell. This mask is applied to the Idle Cell Header field to select the bits
included in the cell filter. A logic 1 in any bit position enables the corresponding bit in the
pattern register to be compared. A logic 0 causes the masking of the corresponding bit. The
default enables the register bit comparison.
MGFC[3:0]:
The MGFC[3:0] bits contain the mask pattern for the first, second, third, and fourth bits of the
first octet of the 53-octet cell. This mask is applied to the Idle Cell Header field to select the
bits included in the cell filter. Logic 1 in any bit position enables the corresponding bit in the
pattern register to be compared. Logic 0 causes the masking of the corresponding bit. The
default enables the register bit comparison.
