SLAVE mode with Master arbitration. In MASTER/SLAVE mode, it is used as the only
Master on the bus or as one of several Masters on the bus with arbitration. In a multi-Mas-
ter environment, the controller switches from MASTER to SLAVE mode on losing arbi-
tration.
Though slave operation is fully supported in MASTER/SLAVE mode, if a device is
intended to operate only as a slave, the SLAVE-ONLY mode is selected. In SLAVE-
ONLY mode, the device does not initiate a transaction even if software inadvertently sets
the START bit.

functions are selected for their respective GPIO ports, the pins are automatically config-
ured for open-drain operation.
The Master is responsible for driving the SCL clock signal. During the Low period of the
clock, a Slave holds the SCL signal Low to suspend the transaction if it is not ready to pro-
ceed. 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

acknowledge, the SDA signal changes in the middle of the Low period of SCL. When
receiving address, data, or acknowledge, the SDA signal is sampled in the middle of the
High period of SCL.
A low-pass digital filter is applied to the SDA and SCL receive signals by setting the filter

interrupt is determined by bits, which are set in the I2CISTAT Register. If the I
ler is disabled, the BRG Controller is used to generate general-purpose timer interrupts.
Each interrupt source other than the baud rate generator interrupt has an associated bit in
the I2CISTAT Register, which clears automatically when software reads the register or
performs some other task such as reading or writing the data register.
