Function Documentation

void usart0_try_read_character

(

void

)

If a character is waiting in the USART hardware buffer, this function reads that character and places it into the input buffer.

This function can be called from within long interrupt service routines that have higher priority than the USART0_RX interrupt, in order to prevent the hardware buffer from overrunning.
