Capture Read/Write Values at Address B

This mode is used to capture the data involved in a read and/or write access to the address
specified by the trigger B, such as the address of a particular control register or program
variable.

Trace Component Window

automatically switched

to

Recorded Data Display

mode.

The trigger address is typically not a program code address (program counter), but rather a
data/memory address.

Access at Address A

This mode is used to capture the data involved in a read and/or write access to the
addresses specified by the trigger A and the trigger B, such as the address of a particular

address.
