	~~4 = 9600~~		:: bits 6:0 = lower 7-bits of the 14-bit prescalar value
	5 = ~~4800~~
	6 = ~~2400~~		The UART's baud rate is determined by the prescalar according to this formula:
			: prescalar = Fsys / baudrate ; Fsys = system clock from {{NextRegNo\|$11}}

			Eg: If the system is HDMI, nextreg 0x11 indicates that Fsys = 27000000. The prescalar for a baud rate of 115200 is 27000000 / 115200 = 234.

1 = 57600
2 = 38400
3 = 19200
4 = 9600
5 = 4800
6 = 2400
