pattern.

octet of the 53-octet cell, in conjunction with the Idle Cell Header and Mask register bits. The
IDLEPASS bit in the RCFP Configuration Register must be set to logic 0 to enable dropping
of cells matching this pattern.
GFC[3:0]:
The GFC[3:0] bits contain the pattern to match in the first, second, third, and fourth bits of the
first octet of the 53-octet cell, in conjunction with the Idle Cell Header and Mask register bits.
The IDLEPASS bit in the RCFP Configuration Register must be set to logic 0 to enable
dropping of cells matching this pattern.
