Revision A1
4.2.8 Programmable Baud Generator (BLL/BHL) (Read/Write)
Two 8-bit registers, BLL and BHL, compose a programmable baud generator that uses 24 MHz to
generate a 1.8461 MHz frequency and divides it by a divisor from 1 to 2
16
-1. The output frequency of
the baud generator is the baud rate multiplied by 16, and this is the base frequency for the transmitter
and receiver. The following table illustrates the use of the baud generator with frequency of 1.8461
Mhz. In high speed UART mode (refer CR0C.bit7 and CR0C.bit6), the programmable baud generator
directly uses 24 MHZ and the divider which is same as normal speed divisor. In the high speed mode,
the data transmission rate can be up to 1.5 M bps.
