Hi,
I single-step thru atmega16 binary with avr-gdb and simulavr in
gdb server mode. I get:

  memory.c:224: WARNING: **** Attempt to read invalid io reg: TCCR1B at 0x004e
  memory.c:259: WARNING: **** Attempt to write invalid io reg: TCCR1B at 0x004e

The atmega16 data sheet shows TCCR1B at 0x4e, so why the error?
