Since the MCU does not respond while execution of the user program is in low-power consumption mode, the values of the RAM and I/O registers displayed in the Memory panel are not updated.

Although CS+ prevents access to memory in low-power consumption mode if this is detected by the debug tool in advance, the MCU does not respond in certain situations, such as immediately before a transition to low-power consumption mode. Since the debug tool internally issues a reset signal to restore communications with the MCU, if you wish to debug a program that may be expected to enter low-power consumption mode, select [No] for the [Update display during the execution] property under the [Access Memory While Running] category on the [Debug Tool Settings] tab of the Property panel.
