, and 16 for the apb1 divider. The output path is used by apb1 peripherals (pclk1, with a maximum frequency of 36 MHz), and the output path is sent to the timer (timer) 2, 3, and 4 frequency divider. The frequency multiplier can be set to 1 or 2. The clock output is used by the Timer 2, 3, and 4. ⑤ Send it to the apb2 divider. Apb2 divider can be divided into 1, 2, 4, 8, and 16. The output channel is used by apb2 peripherals (pclk2, maximum frequency 72 MHz), and the other channel is sent to the

. The software can read the bit 16 (ENF) of AER to determine whether the RTC register can be accessed. 2. Access to RTC can be disabled by writing a password-not value to AER. 2. After each write operation on the RTC register, you must wait until the reg_flag position is 1 before you can write the RTC register. 2.3 RTC Calibration RTC calibration function: When the 32 K crystal oscillator is not punctual, the calibration function is used to calibrate the RTC counter. 2 The RTC engine uses

transferring data between the memory and peripherals. Internal bus of ARM processor After carefully studying the architecture of arm9-based on S3C2410, you will find that, as a high-performance embedded CPU, arm9-can be regarded as a highly concentrated computer system, similar to a computer architecture that splits the nanqiao chip into a multiplier! For details, see: After reading this, we should be able to have some knowledge of the computer's bus. More importantly, we should have a bet

the address access? Nand controller ?), This depends on the system bus arbitration of the device, that is, bus arbitration. Currently, common bus arbitration includes Axi ahba. These bus schedulers are used to plan the physical address space of the processor. Most processor manuals provide their address map, that is, the distribution of peripherals (registers) in the processor address space. For the processor, the virtual address logical address is an input source. The processor converts these

, there are some dedicated data transmission interfaces. The universal control interface converts the write and read cycles of APB bus to specific addresses related to analog front-end control. During the writing or reading of any of these control registers, there is a problem with transmitting data to the analog front-end or from the analog front-end. The dedicated data interface of each Analog block is implemented in the corresponding Digital Block.

entities is the ID field). The Id (primary key) data type can be changed. The default is the Int (int32) type. If you want to define other types for IDs, you should declare the type of ID as shown in the following example. public class person:entity You can set it to string,guid or other data types. The entity class overrides the equality (= =) operator to determine whether two entity objects are equal (the IDs of two entities are equal). A istransient () method is also defined t

give the APB2 divider. APB2 crossover can choose 1, 2, 4, 8, 16, the output of the APB2 peripheral use (PCLK2, the maximum frequency 72MHz), and the other way to the timer (timer) 1 time multiplier used. The multiplier can choose 1 or twice times, the clock output for the timer 1 use. In addition, the APB2 divider has one output for the ADC divider, which is used for the ADC module. ADC divider selectable for 2, 4, 6, 8 Note that the frequency multiplier of the timer, when the division of the
