13.5.3 IIC Control Register (IICC)

Figure 13-7 IIC Control Register (IICC)

IICEN — IIC Enable

The IICEN bit determines whether the IIC module is enabled.

1 = IIC is enabled.

0 = IIC is not enabled.

IICIE — IIC Interrupt Enable

The IICIE bit determines whether an IIC interrupt is requested.

1 = IIC interrupt request enabled.

0 = IIC interrupt request not enabled.

MST — Master Mode Select

The MST bit is changed from a 0 to a 1 when a START signal is generated on the bus and master mode

is selected. When this bit changes from a 1 to a 0 a STOP signal is generated and the mode of operation

changes from master to slave.

1 = Master Mode.

0 = Slave Mode.
