This register allows an arbitrary pointer to be inserted for diagnostic purposes.
APTR[7:0]:
The APTR[7:0] bits, along with the APTR[9:8] bits in the TPOP Arbitrary Pointer MSB Register
are used to set an arbitrary payload pointer value. The arbitrary pointer value is inserted in
the outgoing stream by writing a logic one to the PLD bit in the TPOP Pointer Control
Register.
If the FTPTR bit in the TPOP Pointer Control register is a logic one, the current APTR[9:0]
value is inserted into the payload pointer bytes (H1 and H2) in the transmit stream.
