SC16IS850L
Single UART with I

C-bus/SPI interface
7.8 Programmable baud rate generator
The SC16IS850L UART contains a programmable rational baud rate generator that takes
any clock input and divides it by a divisor in the range between 1 and (2
16
1). The
SC16IS850L offers the capability of dividing the input frequency by rational divisor. The
fractional part of the divisor is controlled by the CLKPRES register in the ‘first extra feature
register set’.
(1)
where:
N is the integer part of the divisor in DLL and DLM registers;
M is the fractional part of the divisor in CLKPRES register;
f
XTAL1
is the clock frequency at XTAL1 pin.
Prescaler = 1 when MCR[7] is set to 0.
Prescaler = 4 when MCR[7] is set to 1.
A single baud rate generator is provided for the transmitter and receiver. The
programmable Baud Rate Generator is capable of operating with a frequency of up to
80 MHz. To obtain maximum data rate, it is necessary to use full rail swing on the clock
input. The SC16IS850L can be configured for internal or external clock operation. For
internal clock operation, an industry standard crystal is connected externally between the
XTAL1 and XTAL2 pins (see
Figure 6
). Alternatively, an external clock can be connected
to the XTAL1 pin (see
Figure 7
) to clock the internal baud rate generator for standard or
custom rates (see
Table 5
).
The generator divides the input 16
clock by any divisor from 1 to (2
16
1). The
SC16IS850L divides the basic external clock by 16. The baud rate is configured via the
CLKPRES, DLL and DLM internal register functions. Customized baud rates can be
achieved by selecting the proper divisor values for the MSB and LSB sections of the baud
rate generator.
Programming the baud rate generator registers CLKPRES, DLM (MSB) and DLL (LSB)
provides a user capability for selecting the desired final baud rate. The example in
Table 5
shows the selectable baud rate table available when using a 1.8432 MHz external clock
input when MCR[7] = 0, and CLKPRES = 0x00.
