work with registers 0x00 to 0x1F only.
ters as data space using LD and ST instructions, $20 must be added to these addresses. The Atmel ATmega16HVB/32HVB
is a complex microcontroller with more peripheral units than can be supported within the 64 location reserved in Opcode for
the IN and OUT instructions. For the Extended I/O space from $60 - $FF in SRAM, only the ST/STS/STD and LD/LDS/LDD
instructions can be used.
