15.4 SIO UART Interface

DoMiNo has two 16550-compatible UARTs. The UARTs have the
following features:

•

Communication speed is up to 256 Kbaud

•

An internal FIFO allows both transmitter and receiver to hold up to
16 bytes of data

•

Hardware flow control (UART1 only)

•

Prescaler

•

DMA registers for four channels (TX and RX for each UART
instance); the DMA Engine takes care of filling data into (TX) and
draining data out of (RX) the UART’s internal FIFOs.

15.4.1 UART Data Frame

shows the composition of the basic UART data frame: one

start bit, eight data bits, one stop bit.

Figure 15.8 UART Data Frame

15.4.2 Baud Rate Generator

The baud rate generator implements two 8-bit registers called Divisor
Latch Registers (DLM and DLL) that can be write-only accessed by the
internal SPARC processor or the external host processor. The processor
can load 16-bit data into DLM and DLL (DLM holds the eight most
significant bits and DLL holds the eight least significant bits) to obtain an
output (nbdout) from the baud rate generator that is 16 times the desired
baud rate. This block implements a 16-bit counter to generate the nbdout
from the input clock. The Divisor value can be calculated as follows
