UART configuration structure.
Data Fields | |
| cy_en_scb_uart_mode_t | uartMode |
| Specifies the UART's mode of operation. | |
| uint32_t | oversample |
| Oversample factor for UART. More... | |
| uint32_t | dataWidth |
| The width of UART data (valid range is 5 to 9) | |
| bool | enableMsbFirst |
| Enables the hardware to shift out data element MSB first; otherwise, LSB first. | |
| cy_en_scb_uart_stop_bits_t | stopBits |
| Specifies the number of stop bits in the UART transaction, in half-bit increments. | |
| cy_en_scb_uart_parity_t | parity |
| Configures the UART parity. | |
| bool | enableInputFilter |
| Enables a digital 3-tap median filter (2 out of 3 voting) to be applied to the input of the RX FIFO to filter glitches on the line (for IrDA, this parameter is ignored) More... | |
| bool | dropOnParityError |
| Enables the hardware to drop data in the RX FIFO when a parity error is detected. | |
| bool | dropOnFrameError |
| Enables the hardware to drop data in the RX FIFO when a frame error is detected. | |
| bool | enableMutliProcessorMode |
| Enables the UART operation in Multi-Processor mode which requires dataWidth to be 9 bits (the 9th bit is used to indicate address byte) | |
| uint32_t | receiverAddress |
| If Multi Processor mode is enabled, this is the address of the RX FIFO. More... | |
| uint32_t | receiverAddressMask |
| This is the address mask for the Multi Processor address. More... | |
| bool | acceptAddrInFifo |
| Enables the hardware to accept the matching address in the RX FIFO. More... | |
| bool | irdaInvertRx |
| Inverts the IrDA RX input. | |
| bool | irdaEnableLowPowerReceiver |
| Enables the low-power receive for IrDA mode. More... | |
| bool | smartCardRetryOnNack |
| Enables retransmission of the frame placed in the TX FIFO when NACK is received in SmartCard mode (for Standard and IrDA , this parameter is ignored) | |
| bool | enableCts |
| Enables the usage of the CTS input signal for the transmitter. More... | |
| cy_en_scb_uart_polarity_t | ctsPolarity |
| Sets the CTS Polarity. | |
| uint32_t | rtsRxFifoLevel |
| When the RX FIFO has fewer entries than rtsRxFifoLevel, the RTS signal is active (note to disable RTS, set this field to zero) | |
| cy_en_scb_uart_polarity_t | rtsPolarity |
| Sets the RTS Polarity. | |
| uint32_t | breakWidth |
| Specifies the number of bits to detect a break condition. | |
| uint32_t | rxFifoTriggerLevel |
| When there are more entries in the RX FIFO than this level the RX trigger output goes high. More... | |
| uint32_t | rxFifoIntEnableMask |
| The bits set in this mask allow the event to cause an interrupt (See UART RX FIFO status. for the set of constants) | |
| uint32_t | txFifoTriggerLevel |
| When there are fewer entries in the TX FIFO then this level the TX trigger output goes high. More... | |
| uint32_t | txFifoIntEnableMask |
| Bits set in this mask allows the event to cause an interrupt (See UART TX FIFO Statuses for the set of constants) | |
| uint32_t cy_stc_scb_uart_config_t::oversample |
Oversample factor for UART.
| bool cy_stc_scb_uart_config_t::enableInputFilter |
Enables a digital 3-tap median filter (2 out of 3 voting) to be applied to the input of the RX FIFO to filter glitches on the line (for IrDA, this parameter is ignored)
| uint32_t cy_stc_scb_uart_config_t::receiverAddress |
If Multi Processor mode is enabled, this is the address of the RX FIFO.
If the address matches, data is accepted into the FIFO. If it does not match, the data is ignored.
| uint32_t cy_stc_scb_uart_config_t::receiverAddressMask |
This is the address mask for the Multi Processor address.
1 indicates that the incoming address must match the corresponding bit in the slave address. A 0 in the mask indicates that the incoming address does not need to match.
| bool cy_stc_scb_uart_config_t::acceptAddrInFifo |
Enables the hardware to accept the matching address in the RX FIFO.
This is useful when the device supports more than one address.
| bool cy_stc_scb_uart_config_t::irdaEnableLowPowerReceiver |
Enables the low-power receive for IrDA mode.
Note that the transmission must be disabled if this mode is enabled.
| bool cy_stc_scb_uart_config_t::enableCts |
Enables the usage of the CTS input signal for the transmitter.
The transmitter waits for CTS to be active before sending data
| uint32_t cy_stc_scb_uart_config_t::rxFifoTriggerLevel |
When there are more entries in the RX FIFO than this level the RX trigger output goes high.
This output can be connected to a DMA channel through a trigger mux. Also, it controls the CY_SCB_UART_RX_TRIGGER interrupt source.
| uint32_t cy_stc_scb_uart_config_t::txFifoTriggerLevel |
When there are fewer entries in the TX FIFO then this level the TX trigger output goes high.
This output can be connected to a DMA channel through a trigger mux. Also, it controls CY_SCB_UART_TX_TRIGGER interrupt source.
