ATmega103 Compatibility Mode of ATMEGA64A-AUR

• One USART instead of two, Asynchronous mode only. Only the eight least significant bits of the Baud Rate Register is available.

• One 16 bits Timer/Counter with two compare registers instead of two 16-bit Timer/Counters with three compare registers.

• Two-wire serial interface is not supported.

• Port C is output only.

• Port G serves alternate functions only (not a general I/O port).

• Port F serves as digital input only in addition to analog input to the ADC.

• Boot Loader capabilities is not supported.

• It is not possible to adjust the frequency of the internal calibrated RC Oscillator.

• The External Memory Interface can not release any Address pins for general I/O, neither configure different wait-states to different External Memory Address sections.

• In addition, there are some other minor differences to make it more compatible to ATmega103:

• Only EXTRF and PORF exists in MCUCSR.

• Timed sequence not required for Watchdog Time-out change.

• External Interrupt pins 3 - 0 serve as level interrupt only.

• USART has no FIFO buffer, so data overrun comes earlier
