INIT_STAT:

The INIT_STAT bit indicates the initialization status of the LASAR-155. When the

INIT bit is set high, the LASAR-155 initializes its internal RAMs and sets the

INIT_STAT bit. The INIT_STAT bit remains set until the LASAR-155 has

completed its initialization procedures. When initialization has completed, the

LASAR-155 sets the INIT_STAT bit low.

INIT:

The INIT bit enables the internal initialization procedures. After startup and after

every reset, the user must force the LASAR-155 to execute its initialization

procedures before configuring the LASAR-155 for AAL Layer processing. When

INIT is set high, the LASAR-155 starts its initialization procedures. Once started,

initialization procedures are performed to completion. The INIT_STAT bit can be

used to indicate when the initialization procedures are complete. The INIT bit

must manually be set low.

The NVPI[3:0] and NVCI[3:0] fields in the COPS Control register must be

set to the desired value before INIT is used to start the internal initialization

procedure. The entire initialization procedure requires a maximum of 20 µs.
