This register contains the status of the pending interrupt requests. An interrupt is
pending if the associated bit has a value of one. Such a pending interrupts can be
manually cleared by writing a 1 to that register bit. Interrupts are automatically cleared
when the corresponding interrupt service routine is being executed.

This register contains the status of additional pending interrupt requests. An interrupt is
pending if the associated bit has a value of one. Such a pending interrupts can be
manually cleared by writing a 1 to that register bit. Interrupts are automatically cleared
when the corresponding interrupt service routine is being executed.
