Table 8-9. SIPNR_L/SIFCR_L/SIMSR_L Bit Assignments (continued)
Table 8-10 defines the bit fields of SIPNR_L.
Bits Name
0–31 INT n Each implemented bit (listed in
received, the interrupt controller sets the corresponding SIPNR bit. When a pending interrupt is handled, the user
clears the SIPNR bit by clearing the corresponding event register bit.
SIPNR bits are read only. Writing to this register has no effect.
Note that the SIPNR bit positions are not changed according to their relative priority.
For unimplemented bits, writes are ignored, read = 0.
