Resets and Interrupts
5.6.4 Software Interrupt (SWI)
5.6.5 Maskable Interrupts
5.6.6 Reset and Interrupt Processing
Technical Data
124
return address for the illegal opcode interrupt is the address of the first
byte of the illegal opcode. Otherwise, it would be almost impossible to
determine whether the illegal opcode had been one or two bytes. The
stacked return address can be used as a pointer to the illegal opcode so
the illegal opcode service routine can evaluate the offending opcode.
SWI is an instruction, and thus cannot be interrupted until complete. SWI
is not inhibited by the global mask bits in the CCR. Because execution
of SWI sets the I mask bit, once an SWI interrupt begins, other interrupts
are inhibited until SWI is complete, or until user software clears the I bit
in the CCR.
The maskable interrupt structure of the MCU can be extended to include
additional external interrupt sources through the IRQ pin. The default
configuration of this pin is a low-level sensitive wired-OR network. When
an event triggers an interrupt, a software accessible interrupt flag is set.
When enabled, this flag causes a constant request for interrupt service.
After the flag is cleared, the service request is released.
