2.2 Synchronous and Asynchronous
In synchronous mode is that the serial data need to
specificed format, 1 start bit, 8 data bits, no parity bit and 1 stop
bit.The data is readed in fixed data format and transimt. The re-
ceiver receive the data and output the data in fixed data format.
In asynchronous mode, the data is sampled and then
transimit. And the receiver received data and regenerate the data
by the sampled data. For the limitation of sampling rate of 32KHz,
the data rate is limited to 14.4Kbps in order to prevent the distor-
tion of the output data. While using asynchronous mode, only RS-
232 interface may work.
