Cautions.
Condition for clearing (SPT = 0)
• Cleared by instruction
• Cleared by loss in arbitration
• Automatically cleared after stop condition is
• When LREL = 1
• When IICE = 0
• After reset
Cautions concerning set timing
• For master reception:
• For master transmission: A stop condition cannot be generated normally during the ACK period. Set
• Cannot be set at the same time as STT.
• SPT can be set only when in master mode
• When WTIM has been set to 0, if SPT is set during the wait period that follows output of eight clocks,

detected
note that a stop condition will be generated during the high-level period of the ninth clock.
When a ninth clock must be output, WTIM should be changed from 0 to 1 during the wait period
following output of eight clocks, and SPT should be set during the wait period that follows output of the
ninth clock.
and wait is canceled, after which TRC is cleared and the SDA line is set to high impedance.
Bit 0 (SPT) is 0 if it is read immediately after data setting.

Stop condition is not generated.
Stop condition is generated (termination of master deviceÕs transfer).
After the SDA line goes to low level, either set the SCL line to high level or wait until it goes to
high level. Next, after the rated amount of time has elapsed, the SDA line is changed from low l
evel to high level and a stop condition is generated.
Cannot be set during transfer.
Can be set only when ACKE has been set to 0 and during the wait period after
slave has been notified of final reception.
