IFR4 is an interrupt flag register for TMOUT. When each flag is set to 1 and the interrupt is
enabled in the corresponding bit of IER4, an interrupt request is generated as specified by the
corresponding bit in ISR4. Clearing is performed by writing 0 to the bit to be cleared. Writing 1 is
not valid and nothing is changed.
