Include: <altera_16550_uart.h>
Parameters: context – device of the UART
Returns: none
Description: Interrupt handler to process UART interrupts to
process receiver/transmit interrupts.
Table 9-19: alt_16550_uart_rxirq
Prototype: static void altera_16550_uart_rxirq (altera_16550_
uart_dev* dev, alt_u32
Include: <altera_16550_uart.h>
Parameters: context – device of the UART
Returns: none
Description: Process a receive interrupt. It transfers the incoming
character into the receiver circular buffer, and sets
the appropriate flags to indicate that there is data
ready to be processed.

uart_dev* dev, alt_u32 status
Include: <altera_16550_uart.h>
Parameters: context – device of the UART
Returns: none
Description: Process a transmit interrupt. It transfers data from
the transmit buffer to the device, and sets the
appropriate flags to indicate that there is data ready
