Description
The 16C550 Single UART Module is exactly what the name suggests. It is a single serial port based around the 16C550 UART chip. An FTDI compatible header connects to serial devices at 115,200 baud. The 16C550 is already supported in RomWBW and will work with the stock 3.4.0 build onwards.
This module is designed to be either a replacement for the now obsolete SIO/2, or as an addition to existing serial modules. In total, up to 8 serial ports can be supported in RomWBW, although you will need to build a custom ROM for anything over 4 serial ports.
The base address is set by a single jumper. If used as the only serial module, then set it at Port 0x80. For the stock build of RomWBW 3.4.0 use port 0xA0 or 0xA8. RomWBW 3.5.0 onwards can use 0x80, 0x88, 0xA0 or 0xA8.
Note that this module is only supported on RomWBW based RC2014 kits, such as the RC2014 Zed and RC2014 Zed Pro. The RC2014 Micro, Mini, Classic or Pro does not currently support this module.
