Register 0x1058, 0x105C: RAPS Link #0 and #1 Configuration
The Receive APS Interface (RAPS) controls the receive APS interface SONET framing. Four
instances of this block is used, one for each APS link.
DOOLI:
LOTI:
SENB:
Reserved:
SDINV:
The DOOLI bit is the data out of lock interrupt status bit. DOOLI is set high when the
DOOLV bit changes state, indicating that either the DRU has locked to the incoming data
stream or has gone out of lock. DOOLI is cleared when this register is read.
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 more than 96 consecutive ones or
zeros received. LOTI is cleared when this register is read.
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. When SENB is a logic one, a loss of transition is
never declared.
These registers must be programmed to logic zero for proper operation.
The signal detect input invert (SDINV) controls the polarity of the SD input. This bit must
be programmed high for proper operation.
