By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processor speed. IAR offers a completely integrated development environment incorporating a compiler, an assembler, a linker and a debugger. Finding the right compiler to support your device is simple:. This collection includes compiler, assembler, linker and Standard C and math libraries. Most of these tools are based on efforts from GNU www.

As inputs, Port B pins that are externally pulled low will source current if the pull-up 2. Port B has better driving capabilities than the other ports. Port C PC Port D PD Port E PE Port F PF Should be connected to the USB D- 2. Reset input. Shorter pulses are not guaranteed to generate a reset. Input to the inverting Oscillator amplifier and input to the internal clock operating circuit. Output from the inverting Oscillator amplifier.
These code examples assume that the part specific header file is included before compilation. For compatibility with future devices, reserved bits should be written to zero if accessed. Some of the status flags are cleared by writing a logical one to them. Errata 8. Thus if VBUS is lower than 4. Changed default configuration for fuse bytes and security byte.
