8.6.1.2 SWI Instruction
8.6.2 Interrupt Status Registers
8.6.2.1 Interrupt Status Register 1
Technical Data
112
NOTE:
Address:
The SWI instruction is a non-maskable instruction that causes an
interrupt regardless of the state of the interrupt mask (I bit) in the
condition code register.
A software interrupt pushes PC onto the stack. A software interrupt does
not push PC–1, as a hardware interrupt does.
The flags in the interrupt status registers identify maskable interrupt
sources.
status register flags that they set. The interrupt status registers can be
useful for debugging.
IF6–IF1 — Interrupt Flags 6–1
Bit 1 and Bit 0 — Always read 0
Reset:
Read:
Write:
These flags indicate the presence of interrupt requests from the
sources shown in
1 = Interrupt request present
0 = No interrupt request present
