SYNTAX
FUNCTION
DESCRIPTION
writes its target address to SPC. The value of SPC allows an exception-handling routine to determine the start
address of the block of scheduled code (called a decision tree) that was executing before the exception was
taken.This operation can be used to save state before idling a task in a multi-tasking environment.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is unchanged.
