Overview:

The SI-M16x50 is an extension of the SI-M16550S UART with FIFOs, with enhancements that emulate features found in similar discrete devices with a range of part numbers. Some of the enhancements are enabled by software and are always present in the design: some – such as maximum FIFO size – are configurable and are selected on compilation.Like the SI-M16550S, the SI-M16x50 offers programmable word length (from five to eight bits), together with an optional parity bit and 1, 1½ or 2 stop bits. If enabled, the parity can be odd, even or forced to a defined state.
