Electronics cours of 4017 lighting IC

The cuors state of the banks is BANK0. As a reminder, Program Counter executes commands stored in the program memory, one after the other.

It is automatically incremented to the next instruction during the current instruction execution. Number of banks may vary depending on the microcontroller; for example, micro PIC16F84 has only two banks.

However, the maximum value isresulting in carry out. The default bank is BANK0. Example of direct addressing: PORTB is an 8-bit wide, bidirectional port. Program Memory – A memory that contains the program which we had writtenafter we’ve burned it.

PORTC is an 8-bit wide, bidirectional port.

Each one of them has a different role. When we need to access a register that is not located inside BANK0, we are required to switch between the banks.


This memory is used to store the program after we burn it to the microcontroller. If we plan to use an interrupt, our program will begin after the Puc Vector; and if not we can start to write from the beginning of the Reset Vector.

These pins have Schmitt Trigger input buffers. Later on, the two methods will be studied in detail.

INDF register is not an actual register it is a virtual register that is not found in any bank. The data is available in the very next cycle in the EEDATA register; therefore, it can be read in the next instruction.

Part of the registers located inside BANK0, and some are not. We are allowed to use the names of the ports without considering their addresses. Program Memory is divided into the pageswhere the program is stored.

Example of indirect addressing: If not set otherwise, then as stated, the default bank is BANK0. Search this web site: The following table demonstrates, which of the Banks the program is working with, based on the selection of the RP0 and RP1 bits: Ccours the IRP Equal to 1, the program will work with banks 2, 3.


Each time we burn program into the micro, we coufs an old program and write a new one. Each bank extends up to 7Fh bytes. Here’s a map of the locations: In the second line we put the number 5 into the working register W, and in the line 3, the content of the W passes to the TEMP variable.

Movlw Addwf0 In this example, we are assigning value of to the W working register. It’s easy to understand, that direct addressing method means working directly with the courw.

Here’s a map of the locations:. In the second line, we put a value into the W register. Register W will contain the reminder: These two memories have separated data buses, which makes the access to each one of them very easy. The following table demonstrates, which of the Banks the program 16876 working with, based on the selection of the RP0 and RP1 bits:.
