CPTR[7:0]:

The CPTR[7:0] bits, along with the CPTR[9:8] bits in the TPOP Current Pointer MSB Register reflect the value of the current payload pointer being inserted in the transmit stream. The value may be changed by loading a new pointer value using the TPOP Arbitrary Pointer LSB and MSB Registers, or by inserting positive and negative pointer movements using the PSE and NSE register bits.
