ASIC and firmware registers normally have multiple fields and they are likely not aligned to nibble boundary. Given register value, find bit and field value is painful especially if you have to do it many times in lab.
Here is a calculator to do it for you. You enter 32bit reg value in 4 bytes. Then give field info by specifying field start (and end) bit index. Bit index is from 31 to 0. Calculator will show the field values.
