Table 17.5 Control Field for Locked Slave Unit
(1)
The master unit can decide the reason the slave unit does not return the acknowledgement (ACK)
by reading the slave status (H'0, H'6). The slave status indicates the result of the last
communications that the slave unit performs. All slave units can provide slave status information.
Figure 17.3 shows bit configuration of the slave status.
