L64724 Registers
Microcontroller Active Flag
The L64724 sets the uC_Active bit to 1 to indicate that
the internal microcontroller is running.
Reserved
The Reserved bit is for LSI Logic internal use only and
must always be set to 0.
Carrier Phase Lock Flag
The L64724 sets the CAR_LC bit to 1 to indicate that the
carrier phase lock detector is locked.
Reserved
This bit is reserved for LSI Logic internal use only. When
read, it returns an indeterminate value.
Stage 3 Synchronization Flag
The L64724 sets the S3 bit to 1 when the Descrambler
synchronization module is in synchronization. When this
bit is 0, the Descrambler module is not synchronized. The
S3 bit is not valid in DSS Mode.
Stage 2 Synchronization Flag
The L64724 sets the S2 bit to 1 when the
Deinterleaver/Reed-Solomon Decoder synchronization
module is in synchronization. When the bit is 0, the
