Toggle Bits in Hardware Register | Dataford Interview Questions

Write a C function to set, clear, and toggle specific bits in a 32-bit hardware register at Benchmark Space Systems.

Implement the equivalent function modify_register(register_value, mask, operation), where all values are unsigned 32-bit integers and operation is "set", "clear", or "toggle". Return the updated 32-bit register value. The mask identifies which bits to modify; all unmasked bits must remain unchanged.

Constraints

0 <= register_value <= 0xFFFFFFFF
0 <= mask <= 0xFFFFFFFF
operation is one of "set", "clear", or "toggle"
Return value must be within the unsigned 32-bit range

Function Signature

def modify_register(register_value, mask, operation):
