Overview
The ADSP-BF50x Blackfin processors feature multiple separate and iden-
tical UART modules.
ADSP-BF50x processors feature two UARTs, referred to as UART0 and
UART1.
The UART modules are full-duplex peripherals compatible with PC-style
industry-standard UARTs, sometimes called Serial Controller Interfaces
(SCI). The UARTs convert data between serial and parallel formats. The
serial communication follows an asynchronous protocol that supports var-
ious word length, stop bits, bit rate, and parity generation options.
