4.4. Global CSR interface Signals

The Global CSR ports are only available when the Remote Access > Configuration Interface parameter is set to Export.
Table 15.  Clock and Reset Signals
Port Name Width Direction Description
global_csr_clk 1 Input Clock input for the Global CSR.
global_csr_reset_n 1 Input Reset input for the Global CSR. This resets all the CSR registers in the Global CSR to their default values.
Table 16.  Sideband AXI4-Lite Signals
Port Name Width Direction Description
