The I2C driver generates call back events that are notified via the function ARM_I2C_SignalEvent.
This section provides the event values for the ARM_I2C_SignalEvent callback function.
The following call back notification events are generated:
| #define ARM_I2C_EVENT_TRANSFER_DONE (1UL << 0) |
Master/Slave Transmit/Receive finished.
| #define ARM_I2C_EVENT_TRANSFER_INCOMPLETE (1UL << 1) |
Master/Slave Transmit/Receive incomplete transfer.
| #define ARM_I2C_EVENT_SLAVE_TRANSMIT (1UL << 2) |
Addressed as Slave Transmitter but transmit operation is not set.
| #define ARM_I2C_EVENT_SLAVE_RECEIVE (1UL << 3) |
Addressed as Slave Receiver but receive operation is not set.
| #define ARM_I2C_EVENT_ADDRESS_NACK (1UL << 4) |
Address not acknowledged from Slave.
| #define ARM_I2C_EVENT_GENERAL_CALL (1UL << 5) |
Slave addressed with general call address.
| #define ARM_I2C_EVENT_ARBITRATION_LOST (1UL << 6) |
Master lost arbitration.
| #define ARM_I2C_EVENT_BUS_ERROR (1UL << 7) |
Bus error detected (START/STOP at illegal position)
| #define ARM_I2C_EVENT_BUS_CLEAR (1UL << 8) |
Bus clear finished.
