MTB CAT1 Peripheral driver library

General Description

Macros to check UART events passed by cy_cb_scb_uart_handle_events_t callback.

Note that only single event is notified by the callback when it is called.

Macro Definition Documentation

◆ CY_SCB_UART_RB_FULL_EVENT

#define CY_SCB_UART_RB_FULL_EVENT   (0x08UL)

The ring buffer is full, there is no more space for additional data.

Additional data is stored in the RX FIFO until it becomes full, at which point data is dropped.

◆ CY_SCB_UART_RECEIVE_ERR_EVENT

#define CY_SCB_UART_RECEIVE_ERR_EVENT   (0x10UL)

An error was detected during the receive operation.

This includes overflow, frame error, or parity error. Check Cy_SCB_UART_GetReceiveStatus to determine the source of the error.

◆ CY_SCB_UART_TRANSMIT_ERR_EVENT

#define CY_SCB_UART_TRANSMIT_ERR_EVENT   (0x20UL)

An error was detected during the transmit operation.

This includes a NACK or lost arbitration. Check Cy_SCB_UART_GetTransmitStatus to determine the source of the error

◆ CY_SCB_UART_RECEIVE_NOT_EMTPY

#define CY_SCB_UART_RECEIVE_NOT_EMTPY   (0x40UL)

The receive fifo is not empty.

To use this event the CY_SCB_RX_INTR_NOT_EMPTY interrupt must be enabled by the user.

◆ CY_SCB_UART_TRANSMIT_EMTPY

#define CY_SCB_UART_TRANSMIT_EMTPY   (0x80UL)

The transmit fifo is empty.

To use this event the CY_SCB_UART_TX_EMPTY interrupt must be enabled by the user.
