Therefore the status bits must always be read before the UDR Register is read. In this case, a dead-lock situation arises.

ATMEGA161 Datasheet

Printed on recycled paper. This means that the following armega161 Interrupt Vectors disappears, and vectors from number 11 to 28 moved up to become vectors number 5 to This will increase noise immunity when using high frequencies. Otherwise the system oscillator will continue to run, drawing additional current. Atmel Corp oration This gives a phase error in the following.

Other terms and product names may be the trademarks of others Printed on recycled paper. San Jose, CA At certain frequencies and voltages, the store program memory SPM instruction may fail.

In C, the only construct that will. 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.

The interpretation of this point of time differs between ATmega and ATmega 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 data sheet for details. The loop may consist of a branch. Atmel’s products are not authorized for use as critical. Programming Interface The Parallel Programming algorithm is changed.

Table 4 shows the ATmega compatible fuse settings. Refer to the data sheet for ATmega for further information. See description in ATmega data sheet for further information. Refer to the ATmega data sheet for details on the changed timing. When the compatibility mode is used, only non-conflicting enhancements make the part different from the ATmega Colorado Springs, Atmegs161 Other terms and product names may be the trademarks of others.

The ATmega has two operating modes selected through the fuse settings. Check the data sheet for detailed information. 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: Scottish Enterprise Technology Park.

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.

Make sure you are using the signature byte of ATmega when porting the design. The following features have been added: TOP does not change the OCx output. The Company assumes no responsibility for any errors.


See the ATmega data sheet for details. Make sure this issue is not harmful to the application. Atm el O pe ra tions.

Changes to Names The following control bits have changed names, but have the same functionality and placement when accessed as in ATmega When the internal Brown-out Detector is enabled, the device may hang in Reset. The calibrated RC Oscillator is assumed to be calibrated to 1. Route des Arsenaux Pointer addresses external memory. Avoid using the SPM instruction. Atmega1161 program counter will be updated with a wrong value.

TEL 1 The timing requirements for Parallel Daatsheet have been changed. The typical frequency of the Watchdog Oscillator in ATmega is close to 1.

PWM not Phase Correct. 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. This dqtasheet 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 error status will be lost.

Additionally, the electrical characteristics of the ATmega are different including an increase in operating frequency because of a change in process technology. Still the following must be kept in mind when the MC Fuse is programmed:
