Cautions regarding set timing
Master receive operation: Setting during transmission is prohibited.
Set ACKE0 = 0; Can be set only after end of receive operation has been notified to slave.
Master send operation: Note that start condition may not be generated normally during ACK period.
Setting at the same time as SPT0 is prohibited.
STT0
0
1
Clear conditions (STT0 = 0)
Note
Cleared with instruction
Cleared upon defeat in arbitration
Cleared after generation of start condition by master
Cleared by RESET input
Set conditions (STT0 = 1)
Set with instruction
Start condition trigger
Doesn't generate start condition.
When bus is released (stop status):
Generates start conditions (activation as master). Changes SDA0 line from high level to low
level and generates start condition. Then secures rated time and sets SCL0 to low level.
When not participating on bus:
Functions as start condition reservation flag. When set, automatically generates start condition
after bus is released.
Note
This flag's signals are made invalid by setting SMBE0 = 0.
