69. Extract Bit Field from 16-bit Register

Your task is to:

• Read a uint16_t register value
• Extract the 5-bit field from bits 4 to 8 (LSB = bit 0)
• Return the value of that field as an unsigned integer
   

Example-1

Input: 0x01F0
Output: 31

(Binary = 0000 0001 1111 0000 → bits 4–8 are all 1)

Example-2

Input: 0x0000
Output: 0

Example-3

Input: 0x00B0
Output: 11

(Binary = 0000 0000 1011 0000 → bits 4–8 = 01011)
