20.5.6.4 Bus IDLE Timeout
Bus Idle timer can be used to define the bus free time (TBUF) between Stop and Start. Bus free time, depending on the baud rate, should be loaded to BITOPR (I2CXBITO[23:0]) and then the bus idle timer should be enabled by setting BITE (I2CxCON2[16]). The bus Idle timeout starts when the host software initiates a Start condition. BITO (I2CxSTAT2[20]) will be set after the defined bus Idle time. BITIE (I2CxINTC[20]) bit can be enabled to generate a generic interrupt (I2CxIF).
