On-chip Breakpoints
The following list gives an overview of the usage of the on-chip breakpoints by TRACE32-ICD:
•CPU family
• Instruction breakpoints: Number of on-chip breakpoints that can be used for program and spot
breakpoints
• Read/Write breakpoints: Number of on-chip breakpoints that can be used as read or write
breakpoints. Can be only set on 8 byte boundaries
• Data breakpoints: Number of on-chip data breakpoints that can be used to stop the program
when a specific data value is written to an address or when a specific data value is read from an
address.
NOTE: On-chip breakpoints can be cleared by the target application or by a target reset. If an on-chip
breakpoint is not hit, first check (with the peripheral view), if the on-chip breakpoint is set or not.
