Description
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
Status when reading:
0: Semaphore was already taken
1: Semaphore was available and hence taken by this read access
Reading the register causes it to change value to 0. Releasing the
semaphore is done by writing 1.
