Operation when the card cover of CPU unit opens

The following operations are performed when the card cover is opened during the trace operation.

Operation of system flags

• The data recording active system variables (sys_bIsLog0DataRecordingActive–sys_bIsLog15DataRecordingActive) and the SD card logging active system variables (sys_bIsLog0LoggingToSDCardActive–sys_bIsLog15LoggingToSDCardActive) stay TRUE while the card cover is open.

• Although the data recording active system variables (sys_bIsLog0DataRecordingActive–sys_bIsLog15DataRecordingActive) turn to FALSE once the trace stop condition is met, the SD card logging active system variables (sys_bIsLog0LoggingToSDCardActive–sys_bIsLog15LoggingToSDCardActive) stay TRUE.

• When the card cover is closed, the SD card logging active system variables (sys_bIsLog0LoggingToSDCardActive–sys_bIsLog15LoggingToSDCardActive) also turn to FALSE.

• The traced data continues to be stored in the buffer (RAM) even when no SD card is inserted. Once the buffer (RAM) becomes full, the buffer overflow variables sys_bIsLog0BufferOverflow–sys_bIsLog15BufferOverflow turn to TRUE.

File status in SD card

• If data cannot be written to an SD card after the completion of trace, the data recording error flags sys_bIsLog0OperationError–sys_bIsLog15OperationError turn to TRUE, and sampling ends.
