Initialize EUSART when used in UART mode with the low frequency clock.

Initialize EUSART when used in UART mode with the low frequency clock.

Note

• (1) When EUSART oversampling is set to eusartOVS0 (Disable), the peripheral clock frequency must be at least three times higher than the chosen baud rate. In LF, max input clock is 32768 (LFXO or LFRCO), thus 32768 / 3 ~ 9600 baudrate.

EUSART_Rx#

uint8_t EUSART_Rx (EUSART_TypeDef * eusart)

Receive one 8 bit frame, (or part of 9 bit frame).

Note

• This function is normally used to receive one frame when operating with frame length of 8 bits. See EUSART_RxExt() for reception of 9 bit frames. Notice that possible parity/stop bits are not considered a part of the specified frame bit length.

• This function will stall if buffer is empty until data is received.

Returns

• Data received.

Receive one 8 bit frame, (or part of 9 bit frame).

Note

• (1) Handles the case where the RX Fifo Watermark has been set to N frames, and when N is greater than one. Attempt to read a frame from the RX Fifo. If the read is unsuccessful (i.e. no frames in the RX fifo), the RXFU interrupt flag is set. If the flag is set, wait to read again until the RXFL status flag is set, indicating there are N frames in the RX Fifo, where N is equal to the RX watermark level. Once there are N frames in the Fifo, read and return one frame. For consecutive N-1 reads there will be data available in the Fifo. Therefore, the RXUF interrupt will not be triggered eliminating delays between reads and sending N data frames in "bursts".

EUSART_RxExt#

uint16_t EUSART_RxExt (EUSART_TypeDef * eusart)

Receive one 8-16 bit frame with extended information.

Note

• This function is normally used to receive one frame and additional RX status information.

• This function will stall if buffer is empty until data is received.

Returns

• Data received and receive status.

Receive one 8-16 bit frame with extended information.

EUSART_Tx#

void EUSART_Tx (EUSART_TypeDef * eusart, uint8_t data)

Transmit one frame.

Note

• Depending on the frame length configuration, 8 (least significant) bits from data are transmitted. If the frame length is 9, 8 bits are transmitted from data. See EUSART_TxExt() for transmitting 9 bit frame with full control of all 9 bits.

• This function will stall if the 4 frame FIFO is full, until the buffer becomes available.

Transmit one frame.

EUSART_TxExt#

void EUSART_TxExt (EUSART_TypeDef * eusart, uint16_t data)

Transmit one 8-9 bit frame with extended control.

Note

• Possible parity/stop bits in asynchronous mode are not considered part of a specified frame bit length.

• This function will stall if buffer is full until the buffer becomes available.

Transmit one 8-9 bit frame with extended control.

EUSART_Spi_TxRx#

uint16_t EUSART_Spi_TxRx (EUSART_TypeDef * eusart, uint16_t data)

Note

• SPI master mode only.
