I2C error Is there a way to thow and catch this error?

Thanks @Gordon for the prompt reply.
I'll try your suggestions later today.
It may be a bit more complex but that makes it fun. (see snippet)
Send reset or change clock and then catch the error and retry on a subsequent read of a status register using the snippet.

/** Readbyte(BusAddress,SubAddress) */
BNO055.prototype.ReadByte=function(subAddress){
 var data=Uint8Array(1);
 this.i2c.writeTo(this.BusAddress, subAddress);
 data=this.i2c.readFrom(this.BusAddress, 1);
 return data[0];
};//end ReadByte
