Single UART with I

C-bus/SPI interface, 64-byte FIFOs, IrDA SIR
Figure 14
shows the internal prescaler and baud rate generator circuitry.
DLL and DLH must be written to in order to program the baud rate. DLL and DLH are the
least significant and most significant byte of the baud rate divisor. If DLL and DLH are both
zero, the UART is effectively disabled, as no baud clock will be generated.
Remark:
The programmable baud rate generator is provided to select both the transmit
and receive clock rates.
Table 7
and
Table 8
show the baud rate and divisor correlation for crystal with frequency
1.8432 MHz and 3.072 MHz, respectively.
Figure 15
shows the crystal clock circuit reference.
