Hi,
AVR IO registers are memory mapped.
For e.g. TCCR0 register is at the address 0x53.
You can use view the contents of this IO register by creating a
pointer to that address and dereferencing it.
Something like: p/x *(uint8_t*)0x53
The memory addresses of the registers can be obtained from the AVR
datasheet.

Hi,
I'm using a JTAGICE II and ice-gdb for debugging. Is there anyway
to read the MCU registers when I hit a breakpoint? I know how to
read the normal registers like r0,r1 etc, but I don't know how to
access the peripheral registers like the timer status registers
etc. Can anyone help?
Thanks,
Simon
