A serial bus interface circuit loses arbitra-
tion when transmitting a slave address. And
receives a slave address of which the value
of the direction bit sent from another master
is "1".
In the slave receiver mode, a serial bus in-
terface circuit receives a slave address of
which the value of the direction bit sent from
the master is "1".
In the slave transmitter mode, 1-word data
is transmitted.
A serial bus interface circuit loses arbitra-
tion when transmitting a slave address. And
receives a slave address of which the value
of the direction bit sent from another master
is "0" or receives a "GENERAL CALL".
A serial bus interface circuit loses arbitra-
tion when transmitting a slave address or
data. And terminates transferring word da-
ta.
In the slave receiver mode, a serial bus in-
terface circuit receives a slave address of
which the value of the direction bit sent from
the master is "0" or receives "GENERAL
CALL".
In the slave receiver mode, a serial bus in-
terface circuit terminates receiving of 1-
word data.

Set the number of bits in 1 word to the BC
and write transmitted data to the SBIDBR.
Test the LRB. If the LRB is set to "1", set the
PIN to "1" since the receiver does not re-
quest next data. Then, clear the TRX to "0"
to release the bus. If the LRB is set to "0",
set the number of bits in 1 word to the BC
and write transmitted data to the SBIDBR
since the receiver requests next data.
Read the SBIDBR for setting the PIN to
"1" (Reading dummy data) or write "1" to the
PIN.
A serial bus interface circuit is changed to
slave mode. To clear AL to "0", read the
SBIDBR or write the data to SBIDBR.
Read the SBIDBR for setting the PIN to
"1" (Reading dummy data) or write "1" to the
PIN.
Set the number of bits in 1-word to the BC
and read received data from the SBIDBR.
