• Control Register
– CCOP Control Register (CCSR)
• Cyclic Code Processing
– CCOP Linear FeedBack Shift Register A–D (CFSR[A:D]),
– CCOP FeedBack Tap Register A–D (CFBT[A:D])
– CCOP FeedForward Tap Register A–D (CFFT[A:D])
– CCOP Bit Select Register A–D (CBSR[A:D])
– CCOP Mask Register A–D (CMSK[A:D])
Note: The Cyclic Code Processing Registers exist in four functionally identical sets
(for instance, CFSRA, CFSRB, CFSRC, and CFSRD are CCOP Linear Feedback
Shift Registers for sets A, B, C, and D, respectively). They are discussed below
generically (for instance, as CFSRz), but each set must be programmed
independently. In the Parity Coding Modes sets C and D are never available,
and B is available only when using both A and B together.
