FAX 1 It is called AS0 elsewhere in that data sheet, as well as everywhere in ATmega The calibrated RC Oscillator is assumed to be calibrated to 1.

Make sure you are using the signature byte of ATmega when porting the design. Other terms and product names may be atmega16 trademarks of others. The Company assumes no responsibility for any errors. This gives a phase error in the following.

datasheet The ATmega has two operating modes selected through the fuse settings. Atmel’s products are not authorized for use as critical. In assembly, insert a nop instruction immediately after a loop to itself.

Changes to Names The following control bits have changed names, but have the same functionality and placement when accessed as in ATmega The only practical problem concerns a loop followed by a two. Table 4 shows the ATmega compatible fuse settings. The following bits have changed locations, but have the same functionality when accessed as in ATmega The program counter will be updated with a wrong value.


The ATmega has a signature byte different from the datashet used in ATmega This will increase noise immunity when using high frequencies. Use external Brown-out Detector and do not enable internal Brown-out Detector. 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.

Avoid using the SPM instruction. See the ATmega data sheet for details.

AVR082 Replacing ATmega161 by ATmega162

Therefore the status bits must always be read before the UDR Register is read. The typical frequency of the Watchdog Oscillator in ATmega is close to 1. Still the following must be kept in mind when the MC Fuse is programmed: The timing requirements for Parallel Programming have been changed. The interpretation of this point of time differs between ATmega and ATmega Colorado Springs, CO 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.

Atmel Cor poration makes no warranty for the use of its products, other than those expressly contained in the Company’s standard warranty. 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 Pointer addresses external memory.

Atme l Headquarte rs. Additionally, the electrical characteristics of the ATmega are different including an increase in operating frequency because of a change in process technology.

PWM not Phase Correct. Some of the fuses are described further in the following sections. Otherwise the system oscillator will continue to run, drawing additional current. In this device, some instructions are not interruptable, and will cause the atmega16.
