AXI4-Stream Trace Control Debug Register - 3.2 English - PG115

This register defines a delay in M_AXIS_ACLK clock cycles after each output packet. This register is a write-only register. Issuing a read request has no effect, and undefined data is read.

This delay is primarily intended to avoid downstream FIFO overflow, which can occur for AXI4-Stream connections that do not implement a ready signal, such as the Zynq® Fabric Trace Monitor interface (see the Zynq-7000 SoC Technical Reference Manual (UG585)).
