The I
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.
Arbitration may be lost in the master transmitter and master receiver modes (see
Figure
0x68, 0x78, and 0xB0 (see
If the STA flag in I2CON is set by the routines which service these states, then, if the bus
is free again, a START condition (state 0x08) is transmitted without intervention by the
CPU, and a retry of the total serial transfer can commence.
In some applications, it may be possible for an uncontrolled source to cause a bus
hang-up. In such situations, the problem may be caused by interference, temporary
interruption of the bus or a temporary short-circuit between SDA and SCL.
