Note: * See section 14.1.3 (1), Slave Status Read (Control Bits: H'0, H'6).
(c) Acknowledge Bit at the End of the Message Length Field
(d) Acknowledge Bit at the End of the Data Field

⎯ When bit 3 in the control bits is 1 (data write) although the slave receive buffer* is not
⎯ When the control bits are set to the data read (H'3, H'7) although the slave transmit buffer*
⎯ When another unit which locked the slave unit requests H'3, H'6, H'7, H'A, H'B, H'E, or
⎯ When the control bits are the locked address read (H'4, H'5) although the unit is not locked
⎯ When a timing error occurs
⎯ When the control bits are undefined
The acknowledge bit at the end of the message length field becomes NAK in the following
cases and transfer is stopped.
⎯ When the parity of the message length bits is incorrect
⎯ When a timing error occurs
The acknowledge bit at the end of the data field becomes NAK in the following cases and
transfer is stopped.
⎯ When the parity of the data bits is incorrect*
⎯ When a timing error occurs after the previous transfer of the acknowledge bit
⎯ When the receive buffer becomes full and cannot accept further data
empty
is empty
H'F in the control bits although the slave unit has been locked
maximum number of transfer bytes if the number of data does not exceed the
maximum number of transfer bytes in one frame.
