Notes:
When a data register is specified as S1, do not change the data register value while PING instruction is executed.
•
The FC6A Series MicroSmart does not respond to a ping packet that is sent by itself.
•
The operation status includes the operation transition state (status code) and the error detail (error code). The status code can be
obtained by masking the least 4 bits of the operation status. The error code is stored in the least 4 bits of the operation status.
