together with the block base address and offset listed in
There are two complete sets of DUART registers (one for UART0 and one for UART1). The two UARTs
on the device are identical, except that the registers for UART0 are located at offset 0x4500 (local), and
the registers for UART1 are located at offset 0x4600 (local). Throughout this chapter, the registers are
described by a singular acronym: for example, LCR represents the line control register for either UART0
or UART1.
The registers in each UART interface are used for configuration, control, and status. The divisor latch
access bit, ULCR[DLAB], is used to access the divisor latch least- and most-significant bit registers and
the alternate function register. Refer to
more information on ULCR[DLAB].
All the DUART registers are one byte wide. Reads and writes to these registers must be byte-wide
operations.
detailed information about each register. Undefined byte address spaces within offset 0x000–0xFFF are
reserved.
In this table and in the register figures and field descriptions, the following access definitions apply:

Signal
Reserved fields are always ignored for the purposes of determining access type.
R/W, R, and W (read/write, read only, and write only) indicate that all the non-reserved fields in a
register have the same access type.
w1c indicates that all of the non-reserved fields in a register are cleared by writing ones to them.
Mixed indicates a combination of access types.
Special is used when no other category applies. In this case the register figure and field description
table should be read carefully.

Request to send. UART_RTSx are active-low output signals that can be programmed to be
automatically negated and asserted by either the receiver or transmitter. When connected to the
clear-to-send (CTS) input of a transmitter, this signal can be used to control serial data flow.
