// Description: Erase the EEPROM sector at the specified address.
// Parameters:EE_address: The address of the sector EEPROM to be erased.
// Return: non.
// Version: V1.0, 2013-5-10

changed, it is not necessary to send the command again

// Parameters:EE_address: Write the first address of the EEPROM.
// DataAddress: The first address of the buffer where the source data is written.
// number: The length of bytes written.
// Return: non.
