I/O buffer question

[vonNeumann]

I was going through arnezami's reboot source and noticed his putch and getch functions reference the address 0x8000_0200_ea00_1010 and the next 8 bytes. I was wondering why this address is used and what it maps to. If this question is below this section's "technical" requirements then please move it.

Thanks

That's the serial output.

Ah. Thanks,

I also found good information in the "Understanding Hello.s" thread in important links and threads in case anyone else reading this wants to know.
