... Overview ATtiny261A/461A/861A are low-power CMOS 8-bit microcontrollers based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the devices achieve throughputs approaching 1 MIPS per MHz allowing the system designer to opti- mize power consumption versus processing speed. 2.1 Block Diagram Figure 2-1 ...

... Some of the Status Flags are cleared by writing a logical one to them. Note that, unlike most other AVRs, the CBI and SBI instructions will only operation 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. ATtiny261A/461A/861A 8 8197CS–AVR–05/11 ...
