SIN, SOUT, ATN are RS-232 communication pins used to interface with a PC for downloading, debugging, monitoring, and serial communication. All Cubloc models have SOUT, SIN, and ATN pins and are connected to a DB-9 connector (PC serial port) as shown below.
Other pins are mostly I/O ports. The user may select which ports (pins) to use as INPUT or OUTPUT. When set to INPUT, the pin enters a high-impedance state; when set to OUTPUT, the pin either outputs logic-low or logic-high. The maximum current (source/sink) available from the output ports is 25mA. The user is free to choose which I/O ports he/she will use for which purpose (such as ADC, PWM, etc…).
