interrupt request of level 2. The interrupts labelled “low” in the interrupt handler are
routed to this interrupt level. This bit has to be cleared when the interrupt is served.
interrupt request of level 1. The interrupts labelled “mid” in the interrupt handler are
routed to this interrupt level. This bit has to be cleared when the interrupt is served.
interrupt request of level 0. The interrupts labelled “hig” in the interrupt handler are
routed to this interrupt level. This bit has to be cleared when the interrupt is served.
event request of level 1. The events labelled “low” in the event handler are routed to
this event level. This bit has to be cleared when the event is served.
event request of level 1. The events labelled “hig” in the event handler are routed to
this event level. This bit has to be cleared when the event is served.

This flag is used in shift or arithmetic operations.
For a shift operation, it has the value of the bit that was shifted out (LSB for shift
right, MSB for shift left).
For an arithmetic operation with unsigned numbers:
This flag is used in shift or arithmetic operations.
For arithmetic or shift operations with signed numbers, it is 1 if an overflow or
underflow occurs.
it is 1 at occurrence of an overflow during an addition (or equivalent).
it is 0 at occurrence of an underflow during a subtraction (or equivalent).
