How many configuration bits are in pic18f?

two configuration bits
Data EEPROM Code protection The data EEPROM is protected from external reads and writes by using two configuration bits, CPD and WRTD.

What is the USB frequency through which pic18f4550 operates?

It can work on a varied range of frequency from 31 KHz to 48 MHz.

How do I set configuration bits in Mplab?

xx the configuration bits can be set by going to MPLAB IDE -> Configure -> Configuration bits. There is a check box that allows the user to specify if he wants the Config bits to be set in code (for this the writing specifications from the compiler user guide has to be followed) or to be set from the window.

How many register banks are available in PIC18F4550?

16 banks
Each register in the data memory has a 12-bit address, thus allowing up to 4096 bytes of data memory. The memory space in the PIC18 family is divided into as many as 16 banks that contain 256 bytes each.

Which timer is used in CCP module of PIC18F4550?

Timer 1 or Timer 3 can be chosen to source the CCP module.

How many port lines the PIC18F4550 has?

40 pins of PIC18F4550 are divided into 5 ports.

What is PIC18F4550?

PIC18F4550 is an 8-bit microcontroller manufactured by Microchip with nano-Watt technology with enhanced flash, USB, and high-performance.

What are configuration bits in pic?

Configuration Bits are a collection of binary data located in the Flash program memory of a PIC® microcontroller (MCU). Configuration bits are programmed into the PIC MCU with the application code. These bits are not executable code as their addresses are not accessible by the program counter.

Where are the configuration bits stored?

In the 18F2620, the config bits are stored in flash, but at a high memory location. They’re stored at 0x300001 and upwards. For historical reasons due to the way memory was previously arranged on PIC microcontrollers, config words are numbered with each number having a “high” and “low” byte.

How many bits is PIC18F4550?

PIC18F4550 is an 8-bit microcontroller, on which the board Aurum is centered. The PIC18F4550 (hereafter referred to as 4550) is an 8-bit MCU with Harvard architecture, i.e. it has separate code and data spaces and pathways. It is commonly available in 40-pin DIP, 44-pin TQFP and QFN packages.

What is bank in DDR?

DDR RAM is organized in rows or memory pages. The memory pages are divided into four sections, called banks. Each bank has a kind of register associated with it. In order to address a row of DDR RAM (a memory page), one must specify on the pins both a memory bank and a row address.

What is CCP in PIC18F4550?

PIC18F4550 has a built-in peripheral module called the CCP (Capture/Compare/PWM) module for this purpose. The CCP module in PIC18F4550 supports two independent instances of Capture, Compare and PWM feature.
