Field Documentation

struct fifo spi_uart_bridge::from_uart_fifo

The uart to spi fifo

int spi_uart_bridge::interrupt_driven

flag indicating if the bridge is polled or interrupt driven

uint8_t spi_uart_bridge::inverted_data

the inverted data byte for the transmit side

int spi_uart_bridge::receive_waiting

flag indicating if there is data for us

int spi_uart_bridge::rx_state

the state of the receive side (uart to spi) of the bridge

int spi_uart_bridge::send_data_flow_request

flag indicating if the remote half wants to be told to turn on/off its data flow

struct fifo spi_uart_bridge::to_uart_fifo

The spi to uart fifo

int spi_uart_bridge::tx_old_state

the state of the transmit side before it was stalled by the remote end

int spi_uart_bridge::tx_state

the state of the transmit side (spi to uart) of the bridge
