## General Description

## API Reference
| UART IRDA Low Power Oversample factors
| UART RX FIFO status.
| Macros to check UART RX FIFO status returned by Cy_SCB_UART_GetRxFifoStatus function or assign mask for Cy_SCB_UART_ClearRxFifoStatus function.
| UART TX FIFO Statuses
| Macros to check UART TX FIFO status returned by Cy_SCB_UART_GetTxFifoStatus function or assign mask for Cy_SCB_UART_ClearTxFifoStatus function.
| UART Receive Statuses
| Macros to check current UART receive status returned by Cy_SCB_UART_GetReceiveStatus function.
| UART Transmit Status
| Macros to check current UART transmit status returned by Cy_SCB_UART_GetTransmitStatus function.
| UART Callback Events
| Macros to check UART events passed by cy_cb_scb_uart_handle_events_t callback.

## Macros
#define | CY_SCB_UART_RX_NO_DATA (0xFFFFFFFFUL)
| Data returned by the hardware when an empty RX FIFO is read.
