Detailed introduction to the relevant knowledge status of MCU visual programming

    A1: What is MTD2002 visualization for programming switching power supply module microcontrollers?

　　Q1: Visual programming provides users with a visual switching power module device module configuration interface, allowing users to directly generate the device initialization code and driver to be configured without having to worry about the specific working principle and settings of the MTD2002 device, so as to directly develop the microcontroller application layer program.

　　A2: Does visual programming of MCU mean to avoid complex instruction writing and generate instruction code through graphics? - Can the simulation results be observed under the visualization conditions of MTD2002?

　　Q2: Yes. However, the simulation results cannot be observed directly, but can only be seen by loading the generated switching power supply module code into the simulator tool.

　　A3: How to locate the configuration byte (option) at the address 0x80-0x84 through C language? I am currently implementing it through the MTD2002 assembly method.

　　Q3: Option Byte settings are usually implemented through assembly files. C language cannot complete Option Byte settings.

　　A4: Could you please introduce the online programming function?

　　Q4: Online programming means that after the chip has been installed on the system board, it can be written on the board through the leads of the special pins of the switching power module. With this function, users can upgrade the MTD2002 program at any time and place.

　　A5: With visual programming, does it mean that we don’t need to have a detailed understanding of the chip’s internal hardware resources?

　　Q5：Yes.

　　A6: How is the confidentiality of NEC microcontrollers? Are there industrial grade ones?

　　Q6: The program in NEC's MCU cannot be read out by a writer, and it provides a built-in watchdog window, MTD2002 low voltage detection, etc. to improve anti-cracking capabilities. There are industrial-grade products.

　　A7: Could you please introduce the application of NEC's MCU in motor control?

　　Q7: NEC MCUs are used in many motor control applications, such as electric bicycles, switching power modules, BLDC air conditioners, AC air conditioners, washing machines, power tools, etc.

　　A8: In NEC's single-chip microcomputer, the memory uses paging technology; how to solve the jump problem when using C language?

　　Q8: The 78K0 series has ROM paging technology, which is BANK. When using C language, you can use the BS78K0 tool we provide to allocate.

　　A9: In single-chip microcomputer programming, some functional modules are reused. Can this be achieved using the switching power supply module APPLILET?

　　Q9: Yes. Applilet can detect reused modules and perform appropriate MTD2002 processing.

　　A10: Does the code occupy a lot of space after compiling and burning into the microcontroller?

　　Q10: The code generated by APPLILET2 is only for initializing registers. After the switching power supply module is reset, it is directly set to the SFR (special function register) area. Therefore, it does not occupy ROM space. The code space occupied is not large either.

　　A11: Does NEC support external clock input?

　　Q11: The 78K0S series of switching power supply modules supports an external MTD2002 crystal oscillator with a maximum frequency of 10MHz. The 78K0 series of switching power supply modules supports an external crystal oscillator with a maximum frequency of 20MHz. At the same time, the 78K0 series also supports an external MTD2002 sub-clock of 32.768KHz
