Datasheet
9) ADP1 Registers
These registers are used to set the ADP.
The register address is 24h and the initial value is 0000_0000h.
10) ADP2 Registers
These registers are used for setting of the ADP.
The register address is 28h and the initial value is 0000_0000h.
11) ADP3 Registers
These registers are used for setting of the ADP.
The register address is 2Ch and the initial value is 0000_0000h.
All 32 bits are at segment_base_Low when in Mode0 or 1.
In Mode2, the lower bit (page_size + 8) is at segment_offset, while the upper bit is at segment_base_Low.

Indicates the Transaction Label and is used in a pair with the response
packet to that request packet. (Do not use the tLabel set with ADP for
packets transmitted from the ATF.)
Indicates the priority level of the packet.
In the case of a value other than "0", the transmitter uses priority Arbitration
for this packet.
The bus number of the destination of the packet is represented with 10 bits,
while the node number is represented with 6 bits.
For a continuous area (segment_base_High, segment_base_Low and,
depending on the case, segment_offset), this indicates the address of the
address space of the destination node.
For a continuous area (segment_base_High, segment_base_Low), this
indicates the address of the address space of the destination node. This
address must be in word units when the Control register AIDT16 = "1" in Mode1.
For 3 continuous areas (segment_base_High, segment_base_Low,
segment_offset), this indicates the address of the address space of the
destination node. This address must be in word units when the Control
register AIDT16 = "1".
In the case of Mode2 that supports transfer by page_table, this indicates the
lower bit of the first address of the element. It also sets the segment_offset
value of ORB.
