5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.) with 64-byte FIFOs
UART1 begins transmission and sends 52 characters, at which point UART2 will generate
an interrupt to its processor to service the RCV FIFO, but assumes the interrupt latency is
fairly long. UART1 will continue sending characters until a total of 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
st
character while 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.

Remark:
Registers DLL, DLH, SPR, Xon1, Xon2, Xoff1, Xoff2 are not reset by the
top-level reset signal RESET, that is, they hold their initialization values during reset.
