8 INTERFACES
8.1 UART
The UART is compliant to the industry-standard 16550 and is used for serial communication with
a peripheral, modem (data carrier equipment, DCE) or data set. Data is written from a master
(CPU) over the APB bus to the UART and it is converted to serial form and transmitted to the
destination device. Serial data is also received by the UART and stored for the master (CPU) to
read back. There is no DMA support on the UART block since its contains internal FIFOs. Both
UARTs support hardware flow control signals (RTS, CTS, DTR, DSR).
Features
 16 bytes Transmit and receive FIFOs.
 Hardware flow control support (CTS/RTS)
 Shadow registers to reduce software overhead and also include a software
programmable reset
 Transmitter Holding Register Empty (THRE) interrupt mode
 IrDA 1.0 SIR mode supporting low power mode.
 Functionality based on the 16550 industry standard:
 Programmable character properties, such as number of data bits per character (5-
8), optional
 parity bit (with odd or even select) and number of stop bits (1, 1.5 or 2)
 Line break generation and detection
 Prioritized interrupt identification
 Programmable serial data baud rate as calculated by the following: baud rate =
(serial clock frequency)/(divisor).
