Note: 1. In ATA6289 only bits SP9, SP8 are in use.
For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses
should never be written.
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.
Some of the status flags are cleared by writing a logic one to them. Note that, unlike most other Atmel^® AVR^®s, the CBI and
SBI instructions 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.
When using the I/O specific commands IN and OUT, the I/O addresses 0x00 - 0x3F must be used. When addressing I/O
registers as data space using LD and ST instructions, 0x20 must be added to these addresses. The ATA6289 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 0x60 - 0xFF in SRAM, only the ST/STS/STD and LD/LDS/LDD
instructions can be used.
