Notes
z Note on the trace start condition
When setting an event (other than “Go”) for the trace start condition, a data when the event is encountered is not
recorded to the trace data. The data of the event which is encountered the next time is recorded.
z Notes on the trace stop condition
When the trace start and trace stop conditions occur simultaneously, the trace stop condition becomes invalid.
When setting other than “Break” for the trace stop condition, the display contents of the Trace window will not be
updated until the user program stops even after a trace stop condition is encountered.
z Note on setting the Event A
When setting an event for the Event A, you cannot specify a mask for an address and data simultaneously. If you
mask them simultaneously, an event will not be encountered.
z Note on setting an event
Do not specify the following addresses as the address of the event. Otherwise, an unauthorized break may occur.
- Address in the interrupt vector table
- Address set in the interrupt vector table (interrupt routine start address)
- Branch address of the branch instruction
Both fixed vector table and variable vector table are included with the interrupt vector table above.
