Operation
SDA and SCL Signals
Table 119. I
The I
mode, or with master arbitration. In MASTER/SLAVE mode, it can be used as the only
Master on the bus or as one of the several masters on the bus, with arbitration. In a
Multi-Master environment, the controller switches from MASTER to SLAVE mode on
losing arbitration.
Though slave operation is fully supported in MASTER/SLAVE mode, if a device is
intended to operate only as a slave, then SLAVE ONLY mode can be selected. In SLAVE
ONLY mode, the device will not initiate a transaction, even if the software inadvertently
sets the START bit.
The I
with most-significant bit first. SCL is the clock for the I
pin alternate functions are selected for their respective GPIO ports, the pins are
automatically configured for open-drain operation.
The Master is responsible for driving the SCL clock signal. During the Low period of the
clock, a slave can hold the SCL signal Low to suspend the transaction if it is not ready to
proceed. The Master releases the clock at the end of the Low period and notices that the
clock remains Low instead of returning to a High level. When the slave releases the clock,
the I
the amount of data transferred in one operation. When transmitting address, data, or an
Acknowledge, the SDA signal changes in the middle of the Low period of SCL
receiving address, Data, or an Acknowledge; the SDA signal is sampled in the middle of
the High period of SCL.
