Product data
6.4 Reset
60 characters have been sent. At this time, UART2 will transmit a 0F to UART1,
informing UART1 to halt transmission. UART1 will likely send the 61
UART2 is sending the Xoff character. Now UART2 is serviced and the processor
reads enough data out of the RX FIFO that the level drops to 32. UART2 will now
send a 0D to UART1, informing UART1 to resume transmission.
