The character is then automatically framed with the start bit, parity bit, correct number of stop bits, and put into the transmit data buffer register.
Control Words There are two types of control word. Mode instruction setting of function 2. Command setting of operation. Mode Instruction 1 Mode Instruction Mode instruction is used for setting the function of the Mode instruction will be in "wait for write" at either internal reset or external reset.
That is, the writing of a control word after resetting will be recognized as a "mode instruction. Command Command is used for setting the operation of the It is possible to write a command whenever necessary after writing a mode instruction and sync characters.
Items to be set by command are as follows: Resetting of error flag. Sending to break characters Internal resetting Hunt mode synchronous mode.
