Address
1. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses
2. I/O registers within the address range $00 - $1F are directly bit-accessible using the SBI and CBI instructions. In these reg-

isters, the value of single bits can be checked by using the SBIS and SBIC instructions.
all bits in the I/O register, writing a one back into any flag read as set, thus clearing the flag. The CBI and SBI instructions
work with registers 0x00 to 0x1F only.
ters as data space using LD and ST instructions, $20 must be added to these addresses.
The ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P 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, only the ST/STS/STD and LD/LDS/LDD instructions can be used.
