Objective data sheet
7.13.1.1 Features
7.13.1 UART1
7.13.2 USART0/2/3
7.13 Digital serial peripherals
The LPC1850/30/20/10 contain one UART with standard transmit and receive data lines,
UART1 also provides a full modem control handshake interface and support for
RS-485/9-bit mode allowing both software address detection and automatic address
detection using 9-bit mode.
UART1 includes a fractional baud rate generator. Standard baud rates such as 115200 Bd
can be achieved with any crystal frequency above 2 MHz.
The LPC1850/30/20/10 contain three USARTs. In addition to standard transmit and
receive data lines, the USARTs support a synchronous mode.
The USARTs include a fractional baud rate generator. Standard baud rates such as
115200 Bd can be achieved with any crystal frequency above 2 MHz.
