14.1.3
The data filed contents are specified by the control bits.
Table 14.4 Control Bit Contents
Notes: 1. According to the value of bit 3 (MSB), the transfer directions of the message length bits
When the control bits received from another unit which locked are not included in table 14.5, the
slave unit which has been locked by the master unit rejects acceptance of the control bits and does
not return the acknowledge bit.
