Enumeration Type Documentation

◆ cy_en_scb_i2c_status_t

I2C status codes.

Enumerator
CY_SCB_I2C_SUCCESS 

Operation completed successfully.

CY_SCB_I2C_BAD_PARAM 

One or more of input parameters are invalid.

CY_SCB_I2C_MASTER_NOT_READY 

The master is not ready to start a new transaction.

Either the master is still processing a previous transaction or in the master-slave mode, the slave operation is in progress.

CY_SCB_I2C_MASTER_MANUAL_TIMEOUT 

The master operation timed out before completing.

Applicable only for the Master Low-Level functions.

CY_SCB_I2C_MASTER_MANUAL_ADDR_NAK 

The slave NACKed the address.

Applicable only for the Master Low-Level functions.

CY_SCB_I2C_MASTER_MANUAL_NAK 

The slave NACKed the data byte.

Applicable only for the Master Low-Level.

CY_SCB_I2C_MASTER_MANUAL_ARB_LOST 

The master lost arbitration, the transaction was aborted.

Applicable only for the Master Low-Level functions.

CY_SCB_I2C_MASTER_MANUAL_BUS_ERR 

The master detected an erroneous start or stop, the transaction was aborted.

Applicable only for the Master Low-Level functions.

CY_SCB_I2C_MASTER_MANUAL_ABORT_START 

The master transaction was aborted and the slave transaction is on-going because the slave was addressed before the master generated a start.

Applicable only for the Master Low-Level functions.
