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 Pattern Register to select the bits included in the cell filter. A
logic one in any bit position enables the corresponding bit in the pattern
register to be compared. A logic zero causes the masking of the
corresponding bit.
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 Pattern Register to select the bits included in the cell filter. A
logic one in any bit position enables the corresponding bit in the pattern
register to be compared. A logic zero causes the masking of the
corresponding bit.
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 the Idle Cell Header Pattern
Register to select the bits included in the cell filter. A logic one in this bit
position enables the MCLP bit in the pattern register to be compared. A logic
zero causes the masking of the MCLP bit.
