Here’s a map of the locations: Part of the registers located inside BANK0, and some are not. However, the maximum value isresulting in carry out.

Movlw Addwf0 In this example, we are assigning value of to the W working register. To access a register that is located in another bank, one should access it inside the program. The default bank is BANK0. Each one of them has a different role.

The following figure shows the two addressing methods: The following table demonstrates, which of the Banks the program is working with, based on the selection of the RP0 and RP1 bits: Program Memory is divided into the pageswhere the program is stored.

The following table demonstrates, which of the Banks the program is working courss, based on the selection of the RP0 and RP1 bits:. The stack operates as a circular buffer. In order to start programming and build automated system, there is no need to study all the registers of the memory map, but only a few most important ones:.

Pin diagram of PIC16FA To the left you can see the direct addressing method, where the bank selection is made by RP bits and the referencing is made directly from memory Opcode by using the variable name. If you want to set a specific port as exit you must change the state of the TRIS to 0.

At this point there is no need to learn how to use this memory with special registers, because there are functions writing and reading that are ready.

PORTB is an 16f786 wide, bidirectional port. Each time the main program execution starts at address – Reset Vector. When we need to access a register that is not located inside BANK0, we are required to switch between the banks. The stack space is not part of either program or data space and the stack pointer is not readable or writable. Each pin is individually configurable as an input or output.

To the left you can see the direct addressing method, where the bank selection is made by RP bits and the referencing is made directly from memory Opcode by using the variable name.

Each bank extends up to 7Fh bytes. The variables that we store in the Data Memory during the program are deleted after we turn of the micro. It’s easy to understand, that direct addressing method means working directly with the variables.

On devices with bytes, addresses from 80h to FFh are unimplemented. Number of banks may vary depending on the microcontroller; for example, micro PIC16F84 has only two banks. Data Memory is divided into the banks. If not set otherwise, then as stated, the default bank is BANK0.

This memory is not directly mapped in the register file space. Both of these functions are provided by the manufacturer. There are six SFRs used to read and write to this memory: In the second line we put the number 5 into the working register W, and in the line 3, the content of the W 1f6876 to the TEMP variable.

The banks are located inside the RAM, where the special registers and the data located. While program is being executed, it is working with the particular bank. In contrast, Data Memory does not save the information because it needs power in order to maintain the information stored in the chip. INDF register is not an actual register it is a virtual register that is not found in any bank.

The role of the PORT register is to receive the information from an external source e.

The default state of the banks is BANK0. EEDATA will hold this value until another read or until it is written to by the user during a write operation. In fact INDF performs the following: We are pkc to use the names of the ports without considering their addresses.

Example of direct addressing:
