SYNTAX
FUNCTION
DESCRIPTION
serviced. If neither interrupts or exceptions are pending and the LSB of rsrc1 is 0, the DPC, PC, and SPC registers are
set equal to rsrc2. If an interrupt or exception is pending and the LSB of rsrc1 is 0, DPC is set equal to rsrc2 and the
service routine is invoked, where exceptions have priorities over interrupts. If the LSB of rsrc1 is 1, program execution
continues with the next sequential instruction.
condition to the jump. If the LSB of rguard is 1, the instruction executes as previously described; otherwise, the jump
will not be taken and PC, DPC, and SPC are not modified regardless of the value of rsrc1.

Operation
Interruptible indirect jump on false
program execution continues at 0x330 after
first servicing pending interrupts
since r20 is true, program execution contin-
ues with next sequential instruction
since guard is false, program execution con-
tinues with next sequential instruction
program execution continues at 0x8000 after
first servicing pending interrupts
