Is it possible to watch variables and registers in runtime with periodical refresh using RLink-Std or RLink-Pro?

Thanks
Carlo

Hi Carlo,

when the CPU is running, the RLink is not able to get information from the cpu memory or registers. It needs the cpu to be halted (by a breakpoint or a manual stop for example).
So this functionality is not possible, sorry !

The datasheet for the uPSD33xx processor says : "The JTAG Debugger can access MCU registers, data memory, and code memory while the MCU is executing at full speed by cycle-stealing. This means “watch windows” may be displayed and periodically updated on the PC during full speed operation. Registers and data content may also be modified during full speed operation." (Not sure if I should post this here or in the 8051 section)

Any chance of implementing "live watch" using this cycle-stealing method?
