IMPORTANT: 8-bit Microcontroller w/ 64Kbyte Flash and 2Kbyte EEPROM.The Flash Memory is addressed to buffer locations 0-FFFFh.The EEPROM Data Memory is addressed to buffer locations 10000h-107FFh.Erase will clear the Configuration Bits.You may program the Calibration informationto any location in the device through the Device/Configure menu.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 Fuse High Byte and Extended Fuse 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:SUT0 Bit5:SUT1Bit6:BODEN Bit7:BODLEVEL]; Fuse High Byte: [Bit0:BOOTRST Bit1:BOOTSZ0 Bit2:BOOTSZ1Bit3: EESAVE Bit4:CKOPT Bit5:SPIEN Bit6:JTAGEN Bit7:OCDEN];Extended Fuse Byte: [Bit0:WDTON Bit1:M103C].Please refer to the device specifications for detailed information.CAL BYTE ADDRESS menu has been added in Device/Configure to select one of theaddresses (0h-3h) in the signature row high byte for 1 2 4 and 8 MHz internal RC Oscillator Calibration.BLB01..2 has been corrected to BLB02..1 and BLB11..2 has been corrected to BLB12..1 in Device/Configureto correspond the display with the programming bits.
