Because Reading data [0x32..0x37] or reading INT_SOURCE[0x30] register makes clear the data

Interrupt can work only when hw device not request data.

Solution : After device configuration, we need disable request (reading data from device), but stay in ability to send the data independently of ENABLE signal in configuration register. And DISABLE in CTL reg not reset the internal device memory.

Also need check about AXI-Lite transactions may support WSTRB

image

uint8_t *device_ptr = 0x40040000; device_ptr[45] = 0x00;

It supported. We have ability work with 8-bit registers independently

now check ability sending data to device without requestion \
