`// Purpose:`	`// Purpose: This is a simple wrapper around the txuart and rxuart`
	`// modules. The purpose is to make both of those modules`
	`// configurable from a single wishbone address, and capable of receiving`
	`// (or transmitting) via reads (writes) from two other addresses.`
	`//`
	`// It also generates interrupts: a receive interrupt strobe on the clock`
	`// when data is made available, and a transmit not busy level interrupt`
	`// which is held high as long as the transmitter is idle. Both should be`
	`// able to work nicely with the programmable interrupt controllers found`
	`// in the ZipCPU project.`
