ROOLI
DOOLI
DOOLI:
The DOOLI bit is the data out of lock interrupt status bit. DOOLI is set high when the the
DOOLV bit changes state, indicating that either the CRU has locked to the incoming data
stream or has gone out of lock. DOOLI is cleared when this register is read.
ROOLI:
The ROOLI bit is the reference out of lock interrupt status bit. ROOLI is set high when the
ROOLV register changes state, indicating that either the PLL is locked to the reference clock
REFCLK or in out of lock. ROOLI is cleared when this register is read.
LOTI:
The LOTI bit is the loss of transition interrupt status bit. LOTI is set high when a loss of
transition event occurs. A loss of transition is defined as either the SD input set low or more
than 96 consecutive ones or zeros received. LOTI is cleared when this register is read.
SENB:
The loss of signal transition detector enable (SENB) bit enables the declaration of loss of
transition (LOT) when more than 96 consecutive ones or zeros occurs in the receive data.
When SENB is a logic zero, a loss of transition is declared when more than 96 consecutive
ones or zeros occurs in the receive data or when the SD input is low. When SENB is a logic
one, a loss of transition is declared only when the SD input is low.
PFPEN:
The parallel frame pulse enable (PFPEN) enables the parallel frame pulse operation when
the parallel data interface is enabled (LIFSEL is set high). When PFPEN is a logic zero, the
FPIN input is ignored and the SONET/SDH framing is performed on the PIN[7:0] data. When
PFPEN is logic one, the SONET/SDH framer is ignored and the PIN[7:0] bus is assumed to
