7.4 Serial interface RS-232

The JCM-501-E00 has a user-programmable RS-232 interface.

7.4.1 Operating principle

The OS provides a receive buffer and a transmit buffer for the user-program-
mable serial interface. These buffers can be used to adjust the transfer rate be-
tween application program and serial interface.

Block diagram

The following illustration shows the block diagram of the user-programmable se-
rial interface:
