2.11. Serial Interface Circuit

Fig. 2.11 Serial Interface Circuit Diagram

RS-232 is an asynchronous transfer interface, which used with externally connected

personal computer and keyboard unit. JP15 connects to PC serial interface through the

RS-232 cable. RxD is a data receive pin of MCU.

CTS

clear to send

of MCU, which

sends a signal from the external device. TxD is a data output pin of MCU.

RTS

is the

request to send

signal, which sends signal to the external device.
