Q.
I want to use the zone time measurement on PD77, but the [Fetch] button in [set_event] of the time measurement window is not
active (the button is displayed in gray). The only active options are [address], [bit symbol], and [trigger]. Under what conditions is
[Fetch] not available?
A.
[Fetch] is not available in the PD77 specifications. However, a memory read cycle occurs for the instruction fetched during a
pre-fetch. Please use this memory read as a substitute method for the zone time measurement. The necessary steps are listed below.
Select [address] and the following settings:
Address column
Type: Other
Address: input the corresponding address
Operator: ==
Data Column
Access: Read
Compare: Not Specify
●
These same settings should be substituted for the hardware breakpoint settings and tracepoint settings.
