In any trap event, the trap origination address register (PCTRAP) is loaded with the value of the Program Counter (PC) associated with the instruction that caused the trap. However, it is not expected to capture the trap origination address for math error traps when they are disabled. | |||||||||||||||||
| Work around None. Alternatively, enable math error traps, ignore the PCTRAP value and clear PCTRAP before exiting the math error trap handler. This re-enables the PCTRAP to capture the trap origination address of any other traps. | |||||||||||||||||
