What is high byte and low byte?

What is high byte and low byte?

A word is two contiguous bytes starting at any byte address. A word thus contains 16 bits. The bits of a word are numbered from 0 through 15; bit 0 is the least significant bit. The byte containing bit 0 of the word is called the low byte; the byte containing bit 15 is called the high byte.

What is high and low address?

3 Answers. The high and low byte address are the physical address of the data on the EEPROM chip (not the address of the chip itself which can be 7 or 10 bits and comes first). The high and low byte are combined to make the full address (see diagram below).

How many address locations does a 10 bit addressing scheme serve?

Address matching for 10-bit addressing is only up to two addresses.

What is I2C eeprom?

Standard I2C EEPROM products in Industrial-Plus grade 105 °C offer an extended temperature range suited for Smart City and Smart Industry solutions. Up to 2 Mbits with I2C protocol at 1 MHz, products feature up to 4 million write/erase cycles per byte, over 100 million cycles per device and 200 years data retention.

How do you add high byte and low byte?

In hexadecimal, your number is 0x8000 which is 0x80 and 0x00. To get the low byte from the input, use low=input & 0xff and to get the high byte, use high=(input>>8) & 0xff .

What is the highest byte?

As of 2018, the yottabyte (1 septillion bytes) was the largest approved standard size of storage by the System of Units (SI). For context, there are 1,000 terabytes in a petabyte, 1,000 petabytes in an exabyte, 1,000 exabytes in a zettabyte and 1,000 zettabytes in a yottabyte.

How do you decode EEPROM?

Reading from the EEPROM basically follows the same three step process as writing to the EEPROM:

1. Send the Most Significant Byte of the memory address that you want to write to.
2. Send the Least Significant Byte of the memory address that you want to write to.
3. Ask for the data byte at that location.

What is I2C communication with a PIC microcontroller?

I2C COMMUNICATION WITH PIC MICROCONTROLLER. I2C COMMUNICATION WITH PIC MICROCONTROLLER: I²C stands for Inter-Integrated Circuit. It is a short distance serial interface that requires only two bus lines for bi-directional data transfer. It is used for attaching lower speed peripheral ICs to microcontrollers in short distance communication.

Which is the best compiler for I2C communication?

We will see I2C code examples with two popular compilers such as MPLAB XC8 and MikroC Pro. At the start, we will see the introduction of I2C communication. Secondly, we will understand the control and configuration registers of PIC Microcontroller I2C module.

What makes up slave address in PIC microcontroller?

Each slave connected to the bus is software addressable by a unique 7-bit or 10-bit. After the Start condition,the first byte sent is known as Control byte. The first seven bits of the control byte make up the slave address. The first four bits are fixed.

How is communication initiated in an I2C bus?

The master initiates communication by generating a serial clock signal to shift a data frame out, at the same time serial data is being shifted-in to the master. This process is the same whether it’s a read or write operation.
