IMPORTANT: Data Pattern address range 0000h-7FFFh is FLASH Program Memory and 8000h-83FFh is EEPROM Data Memory.The Calibration Byte can be programmed into any address in the Flash memory (from 0000h to 7FFFh)as well as any address in the EEPROM memory (from 8000h to 83FFh).To make use of Calibration Byte in Device Configure set CALIBRATION to ENABLE then setCAL BYTE ADDRESS to select one of theaddresses (0h-3h) in the signature row high byte for 1 2 4 or 8 MHz internal RC Oscillator Calibrationthen set address under CALIBRATION ADDRESS.New devices may automatically calibrate the RC Oscillator.Please set the CALIBRATION option to DISABLE(default) to use automatic calibration.You also can set the fuse from Fuse Low Byte and Fuse High Byteunder Device Configure. The fuses are mapped into the fuse bytes in the followingway. Fuse Low Byte: [Bit0:CKSEL0 Bit1:CKSEL1 Bit2:CKSEL2 Bit3:CKSEL3 Bit4:SUT0 Bit5:SUT1Bit6:BODEN Bit7:BODLEVEL]; Fuse High Byte: [Bit0:BOOTRST Bit1:BOOTSZ0 Bit2:BOOTSZ1Bit3:EESAVE Bit4:CKOPT Bit5:SPIEN Bit6:JTAGEN Bit7:OCDEN].Please refer to the device specifications for detailed information.The device has two lock bits.If LB1 is set further programming of memory and Fuse bits without first erasing the device is disabled.If LB1&LB2 is set verify of memory is also disabled.Erasing the device clears all lockbits. In this algorithm Chip Erase is forced beforeany operation for a device with any lockbits programmed.
