7.8.1 Features
7.9.1 Features
7.8 UART
7.9 SPI serial I/O controller
The LPC1110/11/12/13/14/15 contain one UART.
Support for RS-485/9-bit mode allows both software address detection and automatic
address detection using 9-bit mode.
The UART includes a fractional baud rate generator. Standard baud rates such as
115200 Bd can be achieved with any crystal frequency above 2 MHz.
The LPC1100 and LPC1100L series contain two SPI controllers on the LQFP48 package
and one SPI controller on the HVQFN33/TSSOP28/DIP28/TSSOP20/SO20 packages
(SPI0).
The LPC1100XL series contain two SPI controllers.
Both SPI controllers support SSP features.
The SPI controller is capable of operation on a SSP, 4-wire SSI, or Microwire bus. It can
interact with multiple masters and slaves on the bus. Only a single master and a single
slave can communicate on the bus during a given data transfer. The SPI supports full
duplex transfers, with frames of 4 bits to 16 bits of data flowing from the master to the
slave and from the slave to the master. In practice, often only one of these data flows
carries meaningful data.
