FRMLOFI:

The FRMLOFI bit shows that a transition has occurred on the FRMLOF state.

When FRMLOFI is logic 1, the FRMLOF state has changed since the last

read of this register. The FRMLOFI bit is cleared whenever this register is

read.

FRMLOFE:

The FRMLOFE bit enables the generation of an interrupt due to a change in

the FRMLOF state. When FRMLOFE is a logic 1, the interrupt is enabled.

FRMLOF:

The FRMLOF bit shows the current state of the E3/T3 LOF or the J2

Extended LOF indication (depending on which mode is enabled). When

FRMLOF is logic 1, the framer has lost frame synchronization for greater than

1ms, 2ms, or 3ms depending on the setting of the LOFINT[1:0] bits in the

S/UNI-QJET Receive Configuration register.
