Fig 106. IPR register
28.6.2.5 Interrupt Clear-pending Register
28.6.2.6 Interrupt Priority Registers
Q
The ICPR removes the pending state from interrupts, and shows which interrupts are
pending. See the register summary in
The bit assignments are:
Table 445. ICPR bit assignments
Remark: Writing 1 to an ICPR bit does not affect the active state of the corresponding
interrupt.
The IPR0-IPR7 registers provide an 2-bit priority field for each interrupt. These registers
are only word-accessible. See the register summary in
Each register holds four priority fields as shown:
Table 446. IPR bit assignments
Bits
[31:0]
Bits
[31:24]
[23:16]
[15:8]
[7:0]
•
a disabled interrupt sets the state of that interrupt to pending.

Function
Each priority field holds a priority value, 0-3. The lower the
value, the greater the priority of the corresponding interrupt.
The processor implements only bits[7:6] of each field, bits
[5:0] read as zero and ignore writes.
Function
Interrupt clear-pending bits.
Write:
0 = no effect
1 = removes pending state an interrupt.
Read:
0 = interrupt is not pending
1 = interrupt is pending.
