Macros to check current UART transmit status returned by Cy_SCB_UART_GetTransmitStatus function.
Each UART transmit status is encoded in a separate bit, therefore multiple bits may be set to indicate the current status.
Macros | |
| #define | CY_SCB_UART_TRANSMIT_ACTIVE (0x01UL) |
| The transmit operation started by Cy_SCB_UART_Transmit is in progress. | |
| #define | CY_SCB_UART_TRANSMIT_IN_FIFO (0x02UL) |
| All data elements specified by Cy_SCB_UART_Transmit have been loaded into the TX FIFO. | |
| #define | CY_SCB_UART_TRANSMIT_NACK (SCB_INTR_TX_UART_NACK_Msk) |
| SmartCard only: the transmitter received a NACK. | |
| #define | CY_SCB_UART_TRANSMIT_ARB_LOST (SCB_INTR_TX_UART_ARB_LOST_Msk) |
| SmartCard only: the transmitter lost arbitration. | |
