Address
1. Address bits exceeding EEAMSB
2. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses
3. I/O Registers within the address range 0x00 - 0x1F are directly bit-accessible using the SBI and CBI instructions. In these

registers, the value of single bits can be checked by using the SBIS and SBIC instructions.
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 ATtiny87/167 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 - 0xFF in SRAM, only the ST/STS/STD and LD/LDS/LDD
instructions can be used.
