General Description

Macros to check current I2C master status returned by Cy_SCB_I2C_MasterGetStatus function.

Each I2C master status is encoded in a separate bit, therefore multiple bits may be set to indicate the current status.

Macros
#define	CY_SCB_I2C_MASTER_BUSY (0x00010000u)
	The master is busy executing operation started by Cy_SCB_I2C_MasterRead or Cy_SCB_I2C_MasterWrite.

#define	CY_SCB_I2C_MASTER_WR_IN_FIFO (0x00020000u)
	All Write data has been loaded into the TX FIFO.

#define	CY_SCB_I2C_MASTER_ADDR_NAK (0x00100000u)
	The slave NACKed the address. More...

#define	CY_SCB_I2C_MASTER_DATA_NAK (0x00200000u)
	Write completed before all bytes were sent (last byte was NAKed)

#define	CY_SCB_I2C_MASTER_ARB_LOST (0x00400000u)
	The master lost arbitration, the transaction was aborted.

#define	CY_SCB_I2C_MASTER_BUS_ERR (0x00800000u)
	The master detected an erroneous start or stop, the transaction was aborted.

#define	CY_SCB_I2C_MASTER_ABORT_START (0x01000000u)
	The master transaction was aborted and the slave transaction is on-going because the slave was addressed before the master generated a start.
