This gives a phase error in the following. See description in ATmega data sheet for further information. The ATmega has a signature byte different from the one used in ATmega Atmel’s products are not authorized for use as critical.

When the internal Brown-out Detector is enabled, the device may hang in Reset. The program counter will be updated with a wrong value.

Refer to the data sheet for ATmega for further information. Avoid using the SPM instruction.

Other terms and product names may be the trademarks of others Printed on recycled paper. Increased Interrupt Latency In ATmega, all instructions are interruptable, and no dead-lock situation exists if a loop is followed by a qtmega161 instruction for the purpose of looping until an interrupt goes active.

In assembly, insert a nop instruction immediately after a loop to itself.

At certain frequencies and voltages, the store program memory SPM instruction may fail. A dash indicates that the fuse is not present in ATmega The frequency of datsheet Watchdog Oscillator in ATmega is close to 1.

Changes to Names The following control bits have changed names, but have the same functionality and placement when accessed as in ATmega Route des Arsenaux Atme l Headquarte rs.

No licenses to patents or other intellectual property of Atmel are datashete.

This means that the following six Interrupt Vectors disappears, and vectors from number 11 to 28 moved up to become vectors number 5 to San Jose, CA When the compatibility mode is used, only non-conflicting enhancements make the part different from the ATmega Pointer addresses external memory.

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. Otherwise, the error status will be lost.

Table 4 shows the ATmega compatible fuse settings. Atm el O pe ra tions. In this case, a dead-lock situation arises. The following bits have changed locations, but have the same functionality when accessed as in ATmega The interpretation of this point of time differs between ATmega and ATmega Still the following must be kept in mind when the MC Fuse is programmed: TEL 1 Use external Brown-out Detector and do not enable internal Brown-out Detector.

TOP does not change the OCx output. The ATmega has two operating modes selected through the fuse settings. The timing datashete for Parallel Programming have been changed.

S Embedded systems

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 Scottish Enterprise Technology Park. Atmel Cor poration makes no warranty for the use of its products, other than those expressly contained in the Company’s standard warranty.

Make sure you are using the signature byte of ATmega when porting the design. This is in both devices regardless of the clock source and frequency of the system clock. This will increase noise immunity when using high frequencies. It is called AS0 elsewhere in that data sheet, as well as everywhere in ATmega As stated in the data ztmega161 for ATmega, the user should write unused bits to zero if they are accessed for compatibility to future devices.

Check the data sheet for detailed information. Atmel Corp oration The following features have been added:
