CPTR[9:0]:
The CPTR[9:0] bits reflect the value of the current payload pointer being inserted in the
outgoing 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.
It is recommended the CPTR[9:0] value be software debounced to ensure a correct value is
received.
