2DABAN AUTOMATION

CC1020 transceiver interface to a microcontroller shown in Figure 1. Microcontroller pins P2.6 and P3.4 using two-way synchronization with the CC1020 data interface DIO, DCLK connection.
A bidirectional pin microcontroller with CC1020 the DIO connection for data transmission and reception (input and output). DCLK providing the data timing, must be connected to a microcontroller input.
Data output can choose to use a separate pin. CC1020 time to set the INTERFACE register SEP_DI_DO = 1. In synchronous mode, LOCK pin is used as a data output, and DCLK pins as the asynchronous mode of data output, DIO pin end only for data input.
A microcontroller pin can be used to monitor the PLL lock signal that the LOCK pin. When the PLL is locked, LOCK pin is logic low. It can also be used for carrier detection and monitoring of other internal test signals.
CC1020 can be set to three different forms of data transmission: Synchronous NRZ mode, synchronous Manchester code asynchronous transfer mode and UART mode. These three models have different features, synchronization Manchester the best anti-interference ability, but double the baud rate is lower, asynchronous transfer UART to implement the most simple, but the worst anti-jamming capability, and synchronous NRZ UART is better than the anti-jamming capability , but somewhat less in the synchronous Manchester code, but also realize the difficulty in between. Taking into account the basic support microprocessor UART serial c


ommunication, so I chose this mode, the test results fully able to meet the requirements.

It does this by processing instructions to perform arithmetic and logical operations, bit processing and data transfer operations, input and output operations, program flow control, program sequence, and monitor system behavior. CPU can handle the instruction set is determined by its specific instruction set defined. Each CPU instruction set is unique. CPU by the following basic components: 1) The program flow control unit (FPCS), its functions, or 10 from the memory access instructions and data equipment; * control a given command or command processing; * and the rest of the system part of communication. 2) The instruction execution components (IES) and the most important element - the arithmetic logic unit (ALU). ALU in accordance with its design and function can be realized or comparison operations addition and subtraction multiplication and division; * logical NOT operator, or from one form to another form of transformation, or change or removal of the target; * and, or, XOR or other logical operation; • Other arithmetic or logic operation, or such as left, right, rotate left, rotate right, etc.-bit operation. Figure 1-1 describes a memory that contains 10 devices and used to obtain instructions, data and communication bus system of computer systems (embedded systems) the CPU. Embedded systems can be defined as an embedded operating system software and computer systems, the system used to provide specific products or to provide application-specific part of the product. Bus is active in the system of two sub-components or activities of signaling between components of the set of parallel lines.
