AnnaBridge 171:3a7713b1edbc 722 *
AnnaBridge 171:3a7713b1edbc 723 * Call this API after calling the I2C_SlaveInit() and I2C_SlaveTransferCreateHandle() to start processing
AnnaBridge 171:3a7713b1edbc 724 * transactions driven by an I2C master. The slave monitors the I2C bus and passes events to the
AnnaBridge 171:3a7713b1edbc 725 * callback that was passed into the call to I2C_SlaveTransferCreateHandle(). The callback is always invoked
AnnaBridge 171:3a7713b1edbc 726 * from the interrupt context.
AnnaBridge 171:3a7713b1edbc 727 *
AnnaBridge 171:3a7713b1edbc 728 * The set of events received by the callback is customizable. To do so, set the @a eventMask parameter to
AnnaBridge 171:3a7713b1edbc 729 * the OR'd combination of #i2c_slave_transfer_event_t enumerators for the events you wish to receive.
AnnaBridge 171:3a7713b1edbc 730 * The #kI2C_SlaveTransmitEvent and #kLPI2C_SlaveReceiveEvent events are always enabled and do not need
AnnaBridge 171:3a7713b1edbc 731 * to be included in the mask. Alternatively, pass 0 to get a default set of only the transmit and
AnnaBridge 171:3a7713b1edbc 732 * receive events that are always enabled. In addition, the #kI2C_SlaveAllEvents constant is provided as
AnnaBridge 171:3a7713b1edbc 733 * a convenient way to enable all events.

AnnaBridge 171:3a7713b1edbc 737 * @param eventMask Bit mask formed by OR'ing together #i2c_slave_transfer_event_t enumerators to specify
AnnaBridge 171:3a7713b1edbc 738 * which events to send to the callback. Other accepted values are 0 to get a default set of
AnnaBridge 171:3a7713b1edbc 739 * only the transmit and receive events, and #kI2C_SlaveAllEvents to enable all events.
