Table 4.6. ISPR bit assignments
Bits
Name
Function
[31:0]
SETPEND
Interrupt set-pending bits.
Write:
0 = no effect
1 = changes interrupt state to
pending.Read:
0 = interrupt is not pending
1 = interrupt is pending.
Note
Writing 1 to the ISPR bit corresponding to:
an interrupt that is pending has no effect
a disabled interrupt sets the state of that interrupt to pending.
4.2.5 Interrupt Clear-pending Registers
The ICPR0 and ICPR1 registers remove the pending state from interrupts, and show which interrupts
are pending. See:
the register summary in Table 4.2 (p. 88) for the register attributes
Table 4.3 (p. 89) for which interrupts are controlled by each register.
The bit assignments are:

Name
Function
[31:0]
CLRPEND
Interrupt clear-pending bits.
Write:
0 = no effect
1 = removes pending state an
interrupt.Read:
0 = interrupt is not pending
1 = interrupt is pending.
Note
Writing 1 to an ICPR bit does not affect the active state of the corresponding interrupt.
4.2.6 Interrupt Active Bit Registers
The IABR0 and IABR1 registers indicate which interrupts are active. See:
the register summary in Table 4.2 (p. 88) for the register attributes
Table 4.3 (p. 89) for which interrupts are controlled by each register.
The bit assignments are:
