RR10 bit 6, the 2 clock missing bit, is sometimes erroneously set to indicate that the DPLL
detects a clock edge in two successive tries after hardware reset.
Ignore the first bit 7 value Read from RR10 after reset.
The CRC can not be interpreted from the Receive FIFO when one or two residue bits are
sent. The CRC value is received and checked correctly but is not loaded to the Receive
FIFO. The two types of CRC problems are described below:
•
The last three bytes of the Receive FIFO read:
Bits 6 and 7 of the CRC are lost.
•
The last three bytes of the Receive FIFO read:
Bit 7 of the CRC is lost.
The CRC is received and loaded into the Receive FIFO in other situations (that is, the 0, 3,
4, 5, 6, and 7 residue bits).
The Residue code, RR1 bits 3, 2, and 1, is reported independently of the number of residue
bits sent.
Ignore the CRC value read from the Receive FIFO if one or two residue bits are sent.
Two Residue bits (Residue code is
One Residue Bit (Residue code is
