This document is the installation and operating manual of GSB grease ventilator. It introduces the function, components, packaging, dimensions and capacities, installation steps, electrical requirements, start-up, connection to duct and other contents of the product.
This document serves as a comprehensive technical reference for the AVR Enhanced RISC microcontroller architecture. It details the complete instruction set, including status registers, operand types, and specific instructions for data and program memory access.
The text covers various addressing modes such as register direct, I/O direct, data direct, and indirect addressing with displacement or post-increment. It also explains how to utilize extended registers (RAMPX, RAMPY, RAMPZ) for accessing data spaces larger than 64K bytes.
| Architecture Type | AVR Enhanced RISC microcontroller |
|---|---|
| Extended Data Space Support | MCUs with more than 64K bytes data space |
| Extended Program Space Support | MCUs with more than 64K words (128K bytes) program space |
These registers are concatenated with the X-, Y-, and Z-registers to enable indirect addressing of data spaces larger than 64K bytes.
The Z-register contents specify the constant byte address, while the 15 most significant bits select the word address.
The register is decremented before the operation, and the operand address uses this decremented value.
