[Simulavr-devel] How to read/write IO registers

[Andrey Vasilyev]

Hello, all!

 Could you please help me to understand how to read/write from/to IO registers 
using avr-gdb and simulavr? I mean when run something like:

 ldi r17, (1<<RXCIE)
 out UCSRB, r17

 How can I see what has been written to UCSRB IO register? And how can I change 
that value?

 Something like:

 x/4xb 0x2a
 or
 set {int}0x2a=0x80

 Doesn't work.

 I've been looking for this thing long time now...

 Thank you,
 Andrey.
