The status of the Fuse bits is not affected by Chip Erase. If the RSTDISBL Fuse is programmed, then the programming hardware should apply +12V to PB5 while the ATtiny15L is in Power-on Reset. If not, the part can fail to enter programming mode caused by drive contention on PB0 and/or PB5.

The ATmega48PV has a one-byte calibration value for the internal RC Oscillator. This byte resides in the high byte of address $000 in the signature address space. To make use of this byte, it should be read from this location and written into the normal Flash Program memory. At start-up, the user software must read this Flash location and write the value to the OSCCAL register before unlock microcontroller at89c5132 code.

Atmel’s ATmega48PV offers 1K byte of In-System Reprogrammable Flash Program memory and 64 bytes of in-System Reprogrammable EEPROM Data memory. The ATtiny15L is shipped with the On-chip Flash program and EEPROM data memory arrays in the erased state (i.e., contents = $FF) and ready to be programmed when crack mcu at90s1200 code.

This device supports a High-voltage (12V) Serial Programming mode and a Low-voltage Serial Programming mode. The +12V is used for programming enable only, and no current of significance is drawn by this pin (less than 100 µA).

The Low-voltage Serial Programming mode provides a convenient way to download program and data into the ATmega48PV inside the user’s system.

The program and data memory arrays in the ATtiny15L are programmed byte-by-byte in either programming mode. For the EEPROM, an auto-erase cycle is provided within the self-timed write instruction in the Low-voltage Serial Programming mode.

This section describes how to program and verify Flash program memory, EEPROM data memory, Lock bits and Fuse bits in the ATmega48PV. To program and verify the ATmega48PV in the High-voltage Serial Programming mode, the following sequence is recommended.
