Item Description
Trace interval
[For QD75P and QD75D projects]
Set the trace interval within the range 1 to 256.
The interval is the set value
1.77ms.
[For LD75 projects]

Trigger condition
Choose the actual trace starting condition.
• No condition
Trace starts at the start request of the peripheral device.
• Wait start
Trace actually starts when the start signal (X10/X11/X12/X13) turns on after the start
request from the peripheral device.
Trace stop mode
Choose the trace stopping condition.
• Buffer full
Trace stops when the trace data area becomes full.
• Endless
Trace stops at the stop request of the peripheral device.
• Error stop
Trace stops when an error occurs.
• Trace point
[For QD75P and QD75D projects]
Trace stops when the number of trace points reaches the specified value (1 to 8192).
[For LD75 projects]
Trace stops when the number of trace points reaches the specified value (1 to 16384).
