Product data sheet
6.1 UART A-B functions
6.2 Extended mode (128-byte FIFO)
The SC16C852L is capable of operation up to 5 Mbit/s with an external 80 MHz clock.
With a crystal, the SC16C852L is capable of operation up to 1.5 Mbit/s.
The rich feature set of the SC16C852L is available through internal registers. These
features are: selectable and programmable receive and transmit FIFO trigger levels,
selectable TX and RX baud rates, and modem interface controls, and are all standard
features. Following a power-on reset, an external reset, or a software reset, the
SC16C852L is software compatible with the previous generation, SC16C2550,
SC16C652B, and ST16C2450.
The UART provides the user with the capability to bidirectionally transfer information
between an external CPU, the SC16C852L package, and an external serial device. A
logic 0 (LOW) on chip select pins CSA and/or CSB allows the user to configure, send
data, and/or receive data via UART channels A, B. Individual channel select functions are
shown in
Table 3.
H = HIGH; L = LOW.
Table 4.
H = HIGH; L = LOW.
The device is in the extended mode when any of these four registers contains any value
other than 0: FLWCNTH, FLWCNTL, TXINTLVL, RXINTLVL.
