Description
When writing “1” to this register bit, it clears the correspondent interrupt
request bit.
When reading this register, it returns the interrupt request bit status:
0: It is not the bit that causes the interrupt request on primary interface
1: It is the bit that causes the interrupt request on primary interface
Reset to 0000h
