Notes 1.
Depending on the value of bit 3 (MSB), the transfer direction of the message length bits of the subsequent
message field and data field differs.
When bit 3 is “1”, data are transferred from the master unit to the slave unit.
When bit 3 is “1”, data are transferred from the slave unit to the master unit.
3H, 6H, AH, and BH are control bits that specify locking or unlocking.
If any of undefined values 1H, 2H, 8H, 9H, CH, or DH is transmitted, no acknowledge bit is returned.
2.
A unit locked by the master unit rejects acknowledging the control bits and does not output the acknowledge bit if the
control bits received from the master unit which requested locking is in any other state than that shown in Table 2-4.
