IMPORTANT: Buffer address range 0-7FFFh is FLASH Program Memory and 8000h-83FFh is EEPROM Data Memory.You must set the Secure after programming’ under device options for the secure command to operate properly.Due to parellel programming mode specifications device will only be verified between 4.5V to 5.5V.Erase will clear the Configuration Bits.The Calibration Byte can be programmed into any address in the Flash memory (from 0000h to 7FFFh) as wellas any address in the EEPROM memory (from 8000h to 83FFh).To make use of Calibration Byte set Device/Configure/CALIBRATION to ENABLE then setDevice/Configure/CAL BYTE ADDRESS to select address 0h in the signature row high bytefor 1.0MHz internal RC Oscillator Calibrationthen set address under Device/Configure/CALIBRATION ADDRESS.You also can set the fuse from Fuse Low Byte and Fuse High Byteunder Device/Configure menu. The fuses are mapped into the fuse bytes in the followingway. Fuse Low Byte: [Bit0:CKSEL0 Bit1:CKSEL1 Bit2:CKSEL2 Bit3:CKSEL3 Bit4:RESERVED Bit5:RESERVEDBit6:BODEN Bit7:BODLEVEL]; Fuse High Byte: [Bit0:BOOTRST Bit1:BOOTSZ0 Bit2:BOOTSZ1Bit3:EESAVE Bit4:RESERVED Bit5:SPIEN Bit6:JTAGEN Bit7:OCDEN]. All the RESERVED bits must be set to ‘1’ otherwise it will failverify or compare. Please refer to the device specifications for detailed information. ‘
