When the IRP Equal to 1, the program will work with banks 2, 3. The TRIS register is data direction register which defines if lic specific bit or whole port will be an input or an output. However, the maximum value isresulting in carry out. If we plan to use an interrupt, our program will begin coues the Interrupt Vector; and if not we can start to write from the beginning of the Reset Vector. These pins have Schmitt Trigger input buffers. Register W will contain the reminder: These two memories have separated data buses, which makes the access to each one of them very easy.

Usually 16r876 define the ports at the beginning of the program, and then we use only the given names. The stack operates as a circular buffer. 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. When we need to access a register that is not located inside BANK0, we are required to switch between the banks.

Pc access a register that is located in another bank, one should access it inside the program.

Pin diagram of PIC16FA We can control each port by using an assigned address of specific port, but there is much easier way to control the port.

We can control each port by using an assigned address of specific port, but there is much easier way to control the port. Then, we are adding the value of and the W register together. There are six SFRs used to read and write to this memory: In the second line, we put a value into the W register.

PORTC is an 8-bit wide, bidirectional port. The following figure shows the two addressing methods: Then the user must follow a specific write cougs to initiate the write for each byte.

Program Memory – A memory that contains the program which we had writtenafter we’ve burned it. On devices with bytes, addresses from 80h to FFh are unimplemented.

EEDATA will hold this value until another read or until it is written to by the user during a write operation. In most cases, this register is used to switch between the banks Register Bank Selectbut also has other capabilities.

If not set otherwise, then as stated, the default bank is BANK0. The default bank is BANK0. 16ff876 data is available in the very next cycle in the EEDATA register; therefore, it can be read in the next instruction.

CALL has the address of the first instruction in the subroutine as its operand. In this example, we are assigning value of to the W working register. The running program is working only with one bank at all time. 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:. Part of the registers located inside BANK0, and some are not.

Example of direct addressing: Instead, it 16g876 indirectly addressed through the Special Function Registers. It is automatically incremented to the next instruction during the current instruction execution.

Both of these functions are provided by the manufacturer.

This memory is used to store the program after we burn it to the microcontroller. PORTB is an 8-bit wide, bidirectional port.

The lower locations of each bank are reserved for the Special Function Registers.

At this point 16r876 is no need to learn how to use this memory with special registers, because there are functions writing and reading that are ready. Later on, the two methods will be studied in detail.

Each time we burn program into the micro, we erase an old program and write a new one.
