7.2.4.11 ICTL Main Interrupt Status All Register—MBAR + 0x052C
Bits Name Description
0:3 — Reserved
CSa [x] Critical Interrupt Status All—Indicates all pending interrupts, including the currently active
interrupt (if any). CSa is binary, showing each active interrupt input in its corresponding bit
position. See Note 1.
Number in parenthesis indicates equivalent encoded value in CSe, ICTL PerStat, MainStat,
CritStat Encoded Register.
4 CSa0 indicates IRQ[0] interr upt
5 CSa1 Slice Timer 0 interrupt
6 CSa2 HI_int interrupt
7 CSa3 WakeUp from deep-sleep mode (CCS) interrupt
8:31 — Reserved
Note:
1. No direct mask register is defined for critical interrupts. However, IRQ[0] can be masked by the MEE bit in Reg4, in which
case CSa status does not occur. If only the EENA[0] bit in ICTL Exter nal Enable and External Types
Register is cleared, then CSa status occurs, but controller does not assert a e300 core interrupt.
