Hi, all 

 

During the APP software developing based on NiosII cpu SOPC system, I can call the function IOWR_ALTERA_AVALON_UART_RXDATA(base, data) based on the macro-definition in xxx_BSP/driver/inc/altera_avalon_uart_regs.h.  

The macro-definition is followed: 

 

# define IOWR_ALTERA_AVALON_UART_RXDATA(base, data)  

IOWR(base, ALTERA_AVALON_UART_RXDATA_REG, data) 

 

My trouble is where can i find the prototype of IOWR(base,  

ALTERA_AVALON_UART_RXDATA_REG, data) ? 

 

It is appreciated to reply with key!

IOWR is defined in io.h which should be included by altera_avalon_uart_regs.h
