The status registers provide an indication of the health of the system. These registers are Read-Only and a read operation clears the register.

Status registers are cleared according to the following conditions:

  • Applying s_axi_aresetn clears both TX and RX status registers
  • When a particular status register is read (clear on read)
  • Applying rx_reset clears the RX status registers only
  • Applying tx_reset clears the TX status registers only
