How to use devmem command in debian 11?

Why Debian doesn’t have devmem2

I tried to install devmem using command sudo apt-get install devmem2

I got the following error

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package devmem2

Before the above command, i tried sudo apt-get update

for which I got the output
