Bit 14-5 :
Reserved.
Bit 4-0 : S4-S0
, Poll Status. Indicates the interrupt type of the highest priority pending interrupt.
(Master Mode)
Bit 15 : NSPEC
, Non-Specific EOI.
Set 1: indicates non-specific EOI.
Set 0: indicates the specific EOI interrupt type in S4-S0.
Bit 14-5 :
Reserved.
Bit 4-0: S4-S0
, Source EOI Type. Specifies the EOI type of the interrupt that is currently being processed.
(Slave Mode)
Bit 15-3 :
Reserved.
Bit 2-0 :
L2-L0,
Interrupt Type. Encoded value indicating the priority of the IS(interrupt service) bit to reset. Writes to these
bits cause an EOI to be issued for the interrupt type in slave mode.
(
Slave Mode)
Bit 15-8 :
Reserved
Bit 7-3 : T4-T0,
Interrupt Type.
The following interrupt type of slave mode can be programmed.
Timer 2 interrupt controller : (T4,T3,T2,T1,T0, 1, 0, 1)b
Timer 1 interrupt controller : (T4,T3,T2,T1,T0, 1, 0, 0)b
DMA 1 interrupt controller : (T4,T3,T2,T1,T0, 0, 1, 1)b
