during a serial transfer:
A Repeated START condition may be generated in the master transmitter or master
receiver modes. A special case occurs if another master simultaneously generates a
Repeated START condition (see
either master since they were both transmitting the same data.
If the I
a Repeated START condition itself, it will release the bus, and no interrupt request is
generated. If another master frees the bus by generating a STOP condition, the I
will transmit a normal START condition (state 0x08), and a retry of the total serial data
transfer can commence.
