This register defines the first free location in the AXI4-Master external memory buffer. The register is incremented by
0x50 (20 32-bit words) for every trace packet written to the
external memory buffer. This register is a read-only register. Issuing a write
request has no effect.
If the FS bit is cleared in the AXI4-Master Trace Control Debug register, the current address will wrap around to the low address, defined by the AXI4-Master Trace Buffer Low Address, when it would have incremented past the high address, defined by the AXI4-Master Trace Buffer High Address.
The current address is reset to the low address, defined by the AXI4-Master Trace Buffer Low Address, by writing to the AXI4-Master Trace Control Debug register.

AXI4-Master current address of
memory trace buffer. This is the full address of the first free
location in the buffer. N = C_M_AXI_ADDR_WIDTH-1 |
