Hardware

Serial Ports 1 and 2

The Super I/O (W83627HG) provides the circuitry for two serial ports with TTL compatible. Serial ports 1 (COM1) and 2 (COM2) are provided to the baseboard through connector J3. The serial port features are:

Two individual 16550-compatible UARTs

Programmable word length, stop bits and parity

16-bit programmable baud rate generator

Loop-back mode

Two individual 16-bit FIFOs

The standard serial DB9 cable pin-outs are listed in Table 3-18 for reference along with the J3 connector pins. DB9 connectors can be located on the custom baseboard, as application requires.
