Otherwise the system oscillator will continue to run, drawing additional current. PWM not Phase Correct.

The ATmega has two operating modes selected through the fuse settings. Scottish Enterprise Technology Park. Other terms and product names may be the trademarks of qtmega161. Check the data sheet for detailed information. See the ATmega data sheet for details. Route des Arsenaux Therefore the datashheet bits must always be read before the UDR Register is read. 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.

A dash indicates that the fuse is not present in ATmega Other terms and product names may be the trademarks of others Printed on recycled paper. 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.


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.

This means that the following six Interrupt Vectors disappears, and vectors from number 11 to 28 moved up to become vectors number 5 to Atmel Cor poration makes no warranty for the use of its products, other than those expressly contained in the Company’s standard warranty. The only practical problem concerns a loop followed by a two. The following features are not supported when the ATmega is used in the ATmega compatibility mode: Atmel’s products are not authorized for use as critical.

Changes to Names The following control bits have changed names, but have the same functionality and placement when accessed as in ATmega Still the following must be kept in mind when the MC Fuse is programmed: In C, the only construct that will.

This gives a phase error in the following. Avoid using the SPM instruction. Additionally, the electrical characteristics of the ATmega are different including an increase in operating frequency because of a change in process technology.

Use external Brown-out Detector and do not enable internal Brown-out Detector. Pointer addresses external memory. The loop may consist of a branch. 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 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.


Programming Interface The Parallel Programming algorithm is changed. Aatmega161 Interrupt Latency In ATmega, all instructions are interruptable, and no dead-lock situation exists if a armega161 is followed by a two-word instruction for the purpose of looping until an interrupt goes active.

Table 4 shows the ATmega compatible fuse settings. Make sure you are using the signature byte of ATmega when porting the design. Refer to data sheet for details. In this case, a dead-lock situation arises. Make sure this issue is not harmful to the application. In this device, some instructions are not interruptable, and will cause the interrupt.

Atmel AVR Controller

See description in ATmega data sheet for further information. Printed on recycled paper. Refer to the ATmega data sheet for details on the changed timing. This is in both devices regardless of the clock source and frequency of the system clock. The calibrated RC Oscillator is assumed to be calibrated to 1.

The timing requirements for Parallel Programming have been changed. FAX 1
