7.18.1.1 Features
7.18.2.1 Features
7.18.2 USART0/2/3
7.18.3 SPI serial I/O controller
The LPC4350/30/20/10 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.
The LPC4350/30/20/10 contain one SPI controller. SPI is a full duplex serial interface
designed to handle multiple masters and slaves connected to a given bus. Only a single
master and a single slave can communicate on the interface during a given data transfer.
During a data transfer the master always sends 8 bits to 16 bits of data to the slave, and
the slave always sends 8 bits to 16 bits of data to the master.
