The S_AXI_LITE interface allows you to access the ISP version/soft reset registers, as well as, configure the PL IIC/GPIO instances, if enabled.

Refer to the following register space details of the IIC/GPIO instances.

GPIO

The address to access each register equals the base address of S_AXI_LITE from design plus the address offset.

Note: If different tiles are enabled in different IP instances, the base address for each tile depends on the S_AXI_LITE address of the ISP instance in which it is enabled, but the register offset remains the same.
