Doubt in Section 197 CrPC vs Section 220 IPC - please help!

Yaar samajh nahi aaya, kya main galat hoon? In dono sections me kya farak hai? Section 197 CrPC kehte hain ki koi officer jo apne wajah se apne duty se avrodhit hai woh bhi protection ke liye apply kar sakta hai. Lekin Section 220 IPC kehte hain ki koi officer jo apne duty se avrodh hit hai woh jail mein rakha ja sakta hai. Ye dono ek doosre se alag alag hain ya phir yeh dono ek hi cheez hai? Please clarify karein!
