13.6.2 Interrupt Status Registers
The flags in the interrupt status registers identify maskable interrupt sources.
interrupt sources and the interrupt status register flags that they set. The interrupt status registers can be
useful for debugging.
IF1 and IF3–IF6 — Interrupt Flags
Bit 0, 1, and 3— Always read 0

IF7–I
Freescale Semiconductor
These flags indicate the presence of interrupt requests from the sources shown in
This flag indicates the presence of interrupt requests from the sources shown in
1. The I bit in the condition code register is a global mask for all interrupt sources except the SWI instruction.
