instructions will only operate on the specified bit, and can therefore be used on registers containing such Status Flags. The
CBI and SBI instructions work with registers 0x00 to 0x1F only.
Registers as data space using LD and ST instructions, 0x20 must be added to these addresses. The ATtiny48/88 is a com-
plex 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 0x60
instructions can be used.
