Make sure this issue is not harmful to the application. 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. In assembly, insert a nop instruction immediately after a loop to itself. This is in both devices regardless of the clock source and frequency of the system clock.

See the ATmega data sheet for details. The following features are not supported when the ATmega is used in the ATmega compatibility mode: See description in ATmega data sheet for further information. Printed on recycled paper. In C, the only construct that will. Note that since the crystal oscillator in ATmega does not have a rail-to-rail amplitude, it is not possible to clock other units directly from the XTAL2 pin. Atm el O pe ra tions.
Table 4 shows the ATmega compatible fuse settings. The frequency of the Watchdog Oscillator in ATmega is close to 1. Some of the fuses are described further in the following sections.
In this case, a dead-lock situation arises. Check the data sheet for detailed information. Other terms and product names may be the trademarks of tamega161 Printed on datadheet paper. Avoid using the SPM instruction. Pointer addresses external memory. The Company assumes no responsibility for any errors. This gives a phase error in the following. Changes to Dayasheet The following control bits have changed names, but have the same functionality and placement when accessed as in ATmega Refer to the ATmega data sheet for details on the changed timing.
FAX atmdga161 Additionally, the electrical characteristics of the ATmega are different including an increase in operating frequency because of a change in process technology.
Therefore the status bits must always be read before the UDR Register is read. TEL 1 The loop may consist of a branch. This will increase noise immunity when using high frequencies.

Refer to the data sheet for ATmega for further information. Scottish Enterprise Technology Park.
The typical frequency of the Watchdog Oscillator in ATmega is close to datasheft. In this device, some instructions are not interruptable, and will cause the interrupt. Programming Interface The Parallel Programming algorithm is changed. When the internal Brown-out Detector is enabled, the device may hang in Reset.

Other terms and product names may be the trademarks of others. The interpretation of this point of time differs between ATmega and ATmega A dash indicates that the fuse is not present in ATmega Use external Brown-out Detector and do not enable internal Brown-out Detector. The program counter will be updated with a wrong value. San Jose, CA The following bits have changed locations, but have the same functionality when accessed as in ATmega Route des Arsenaux This means that the selection of Time-out period for the Watchdog Timer in terms of number of WDT Oscillator cycles must be reconsidered when porting the design to ATmega Otherwise the datawheet oscillator will continue to run, drawing additional current.
When the compatibility mode is used, only non-conflicting enhancements make the part different from the ATmega The ATmega has a signature byte different from the one used in ATmega Atmel Cor poration makes no warranty for the use of its products, other than those expressly contained datwsheet the Company’s standard warranty.
