8.10 Confirming the R2 switch states and software version

By reading the R2 buffer memory shown below, the R2 switch state and software
version can be confirmed.
This is effective for confirming the state when the R2 switch settings are correct but the
operation is incorrect.
When using the buffer memory automatic update function to read, refer to section 5.6.
Refer to section 5.7.3 when using the transmission/reception buffer.
