Appendix B. AVR ATmega Control Registers
The register summaries in this appendix are intended as a quick reference. This appendix is not a comprehensive description of each control register. For detailed descriptions of each control register for a particular MCU type, see the Atmel documentation. Pay special attention to the notes included with the control register summaries in the Atmel documents. Each MCU has a slightly different set of things to watch out for.
In general, reserved bits (marked with a “–”) should not be accessed. Registers in the range of 0x00 to 0x1F are directly bit-accessible with the SBI and CBI instructions (set I/O bit and clear I/O bit, respectively). Register addresses in parentheses are the SRAM addresses of the control registers, whereas the addresses not in parentheses reside in the 64-byte address space reserved for I/O control registers. The reserved locations can be used with the IN and OUT instructions, and the SRAM addresses must be accessed with the ST/STS/STD and LD/LDS/LDD instructions.
The information in this appendix was derived from the following Atmel technical documents, all of which are available from Atmel.com:
