Setup Procedure
(19) Judge the ACK bit level.
SC3CTR (x'3FAA')
bp0 : SC3ACKO
(20) Select the transfer bit count.
SC3MD0 (x'3FA8')
bp2-0 : SC3LNG2-0 = 0
(21) Select the start condition.
SC3MD0 (x'3FA8')
bp3 : SC3STE = 0
<The next data transmission is started.>
(22) Serial transmission is started. [
<The transmission is finished.>
<Transaction after IIC communication>
(23) Clear BUSY flag.
SC3CTR (x'3FAA')
bp7 : IICBSY = 0
Note : In the above (5) to (8), (9) to (12), (13) to (14), (15) to (16), (18) to (19) and (20) to (21), settings can
be set at once.
(19) Confirm the level of the ACK bit, received by the
SC3ACKS flag of the serial 3 control register
(SC3CTR). When SC3ACKO = 0, the transmission
is continued. When SC3ACKO = 1, the reception at
slave may be impossible, finish the communication.
(20) If the transfer bit count is changed, set the
transfer count bit by the SC3LNG2-0 flag of the
serial 3 mode register (SC3MD0).
(21) Set the SC3STE flag of the SC3MD0 register to "0"
to disable start condition.
(22) Set the transmission data to SC3TRB to start the
(17)]
transmission. [
(23) Clear the IICBSY flag of the serial 3 control
register (SC3CTR) to "0". Then, the stop condition
is automatically generated to finish the
communication.
