The TL16C752CIPFB is a dual universal asynchronous receivertransmitter (UART) with 64-byte FIFOs, automatic hardware and software flow control, and data ratesup to 3 Mbps. The device offers enhanced features. It has a transmission Character control register(TCR) that stores received FIFO threshold level to start or stop transmission during hardware andsoftware flow control.
With the FIFO RDY register, the software gets the status of TXRDY or RXRDY for all twoports in one access. On-chip status registers provide the user with error indications, operationalstatus, and modem interface control. System interrupts may be tailored to meet user requirements.An internal loop-back capability allows onboard diagnostics. The TL16C752CIPFB incorporates the functionality of two UARTs, each UART having its ownregister set and FIFOs. The two UARTs share only the data bus interface and clock source, otherwisethey operate independently. Another name for the UART function is asynchronous communicationselement (ACE), and these terms are used interchangeably. The bulk of this document describes thebehavior of each ACE, with the understanding that two such devices are incorporated into theTL16C752CIPFB device.
