Changes to Names The following control bits have changed names, but have the same functionality and placement when accessed as in ATmega Otherwise the system oscillator will continue to run, drawing additional current.

The following features have been added: A dash indicates that the fuse is not present in ATmega The following features are not supported when the ATmega is used in the ATmega compatibility mode: In assembly, insert a nop instruction immediately after a loop to datqsheet.

At certain frequencies and voltages, the store program memory SPM instruction may fail. Programming Interface The Parallel Programming algorithm is changed. See description in ATmega data sheet for further datazheet.

The frequency of the Watchdog Oscillator in ATmega is close to 1. Use external Brown-out Datasheeet and do not enable internal Brown-out Detector.

Pointer addresses external memory. PWM not Phase Correct.

The interpretation of this point of time differs between ATmega and ATmega The calibrated RC Oscillator is assumed to be calibrated to 1. The program counter will be updated with a wrong value. As stated in the data sheet for ATmega, the user should write unused bits to zero if they are accessed for compatibility to future devices.

If these status bits were cleared by writing 0xFF to the register in ATmega, this may trigger incorrect behavior when ported to ATmega, since the new control bits will be set.

The only practical problem concerns a loop followed by a two. Some of the fuses are described further in the following sections.

Route des Arsenaux Atmel Cor poration makes no warranty for the use of its products, other than those expressly contained in the Company’s standard warranty. In this device, some instructions are not interruptable, and will cause the interrupt.

When the compatibility mode is used, only non-conflicting enhancements make the part different from the ATmega TEL 1 This will increase noise immunity when using high frequencies. When the MC Fuse is unprogrammed, all new features are supported, but porting the code may require more work. TOP does not change the OCx output. Table 4 shows the ATmega compatible fuse settings. The loop datashret consist of a branch.

When ratasheet internal Brown-out Detector is enabled, the device may hang in Reset. Atm el O pe ra tions. The ATmega has a signature byte different from the one used in ATmega This gives a phase error in the following.
