The loop may consist of a branch. Changes to Names The following control bits have datadheet names, but have the same functionality and placement when accessed as in ATmega In this case, a dead-lock situation arises. TEL 1 Scottish Enterprise Technology Park. Make sure you are using the signature byte of ATmega when porting the design.

Otherwise, the error status will be lost. This will increase noise immunity when stmega161 high frequencies. In this device, some instructions are not interruptable, and will cause the interrupt. Additionally, the electrical characteristics of the ATmega are different including an increase in operating frequency because of a change in process technology.

No licenses to patents or other intellectual property of Atmel are granted. TOP does not change the OCx output. San Jose, CA Make sure this issue is not harmful to the application. Colorado Springs, CO Programming Interface The Parallel Programming algorithm is changed.

Therefore the status bits must always be read before the UDR Register is datashert.

Atmel’s products are not authorized for use as critical. The Company assumes no responsibility for any errors which may appear in this document, reserves the right to change devices or specifications detailed herein at any time without notice, and does not make any commitment to update the information contained herein. The typical frequency of the Watchdog Oscillator in ATmega is close to 1.


At certain frequencies and voltages, the store program memory SPM instruction may fail. Pointer addresses external memory.

The ATmega has two operating modes selected through the fuse settings. Other terms and product names may be the dayasheet of others Printed on recycled paper.

It is called AS0 elsewhere in that data sheet, as well as everywhere in ATmega The only practical problem concerns a loop followed by a two. Avoid using the SPM instruction.

When the internal Brown-out Detector is enabled, the device may hang in Reset. The Company assumes no responsibility for any errors. Table 4 shows the ATmega compatible fuse settings. Other terms and product names atmegs161 be the trademarks of others. Atm el O pe ra tions. Atme l Headquarte rs.

When the MC Fuse is unprogrammed, all new features are supported, but porting the code may require more work. Note that since the crystal oscillator in ATmega does not have a rail-to-rail amplitude, it ddatasheet not possible to clock other units directly from the XTAL2 pin. See the ATmega data sheet for details. The interpretation of this point of time differs between ATmega and ATmega Refer to data sheet for details.

Check the data sheet for detailed information. This is in both devices regardless of the clock source and frequency of the system clock.

In assembly, insert a nop instruction immediately after a loop to itself. FAX 1 Some of the fuses are described further in the following sections. See description in ATmega data sheet for further information. If these status bits were cleared by writing 0xFF to the register in Datahseet, this may trigger incorrect behavior when ported to ATmega, since the new control bits will be set.

The ATmega has a signature byte different from the one used in ATmega A dash indicates that the fuse is not present in ATmega Still the following must be kept in mind when the MC Fuse is programmed: Printed on recycled paper.

Refer to the ATmega data sheet for details on the changed timing. 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 The following features have been added: Atmel Cor poration makes no warranty for the use of its products, other than those expressly contained in the Company’s standard warranty.

No licenses to patents or other intellectual property of Atmel are granted by the Company in connection with the sale of Atmel products, expressly or by implication. The frequency of the Watchdog Oscillator in ATmega is close to 1.
